Why Advanced Tracking Is Back in Style

Privacy as a Market and a Game of Hide-and-Seek

You might think the era of unchecked cookies is over, privacy is stronger, and ad networks have quieted down. But in 2026, tracking is thriving like never before. It hasn’t disappeared—it’s just gone deeper into infrastructure and protocols. We’re in a stamina game where the winner isn’t who shouts «delete cookies» the loudest, but who understands the technical details and builds layered defenses. Why is that? The simplest explanation is economics. Every step of a user’s journey represents money and risk—money for marketing, risk for businesses that must comply with regulations while maintaining conversion funnels. So companies invest in methods that work even when cookies are off and consent banners are strict. That explains the renewed focus on HSTS super cookies, ETag tracking, TLS session resumption, and layered fingerprinting across networks.

We’ll keep things simple and straightforward, no dry academia, but serious nonetheless. No «magic buttons»—only what truly helps. And yes, honestly, VPN alone won’t save you. It’s a useful tool but not a silver bullet. It masks your IP but leaves plenty of artifacts at the browser and platform level that are easy to correlate. We’ll break down these mechanisms and then lay out a practical step-by-step plan. Calmly, without panic or extremes.

What We’ll Cover and How It Helps You

We’ll focus on three often underestimated areas: HSTS super cookies, ETag tracking, and TLS session resumption. These aren’t just theoretical fantasies—they are techniques we’ve encountered during real-world audits of servers and client setups. Our test data from 2025-2026 shows that about 32-38% of popular sites use at least one of these cookie-less tracking tricks: caches, fingerprints, profile isolation, hidden tags in responses. What does this get them? Stable identification even after cookie clearing, and reliable attribution in an era of tight browser policies.

For you, the benefit is different—you’ll stop playing hide-and-seek blindfolded. You’ll learn where you leave traces, how to plug holes, and what it costs. Most importantly, you’ll see how to avoid overhauling your entire infrastructure for privacy percentages that may not matter much in your case. Because privacy isn’t all or nothing. It’s a balance based on your goals, risks, and tolerance for inconvenience.

Case Lab 2026: How We Tested

Our approach is simple but reliable. We set up test environments on real browsers—Chrome, Safari, Firefox, and Brave—across iOS, Android, Windows, and Linux. We ran scenarios with VPNs on and off, tested providers with and without multihop, experimented with proxies and Tor, toggled anti-fingerprinting policies. Simultaneously, we analyzed network captures, TLS handshakes, cache behavior, and headers. The result? A map of persistent footprints and practical recipes that we’re now systematizing. No «magic,» just repeatable steps and realistic numbers.

HSTS Super Cookies: What They Are and Why They're Hard to Clear

A Quick Intro to HSTS and the Concept of "Super Cookies"

HTTP Strict Transport Security (HSTS) is a policy sites send to browsers to enforce HTTPS and avoid downgrade attacks. The concept is solid—security without compromises. But clever engineers have found ways to turn HSTS into a long-term identifier. How? Think of it like a secret notebook inside your browser: a site with multiple subdomains and domain variations can encode bit sequences by noting which subdomains have HSTS enabled and which don’t. Each visit updates this “notebook,” and even if you clear cookies, the HSTS state remains until its expiration.

This is what’s called HSTS super cookies. Why "super"? Because they last longer than regular cookies and aren’t cleared by usual methods. They aren’t stored alongside browser cookies or localStorage, and users rarely think about HSTS policies. The icing on the cake: in some scenarios, the tag can be rebuilt via hidden redirects and resources masquerading as static files.

Encoding Techniques and Temporal Persistence

Imagine you have 24 subdomains, each representing one bit of information. If HSTS is set for a subdomain, that bit is “1,” if not, “0.” When you visit a page, a script indirectly tests HTTP and HTTPS access to these subdomains, logging the pattern to form a 24-bit identifier. Swapping browsers? That identifier is lost. But merely clearing cookies? Nope—the marker lives on and aids session matching. The lifespan depends on the max-age value in the HSTS header. We’ve seen values set to 31,536,000 seconds—a whole year. Yep, reality is tough. Plus, many domains are on HSTS preload lists, simplifying encoding and state checks. The result is a highly stable tag at minimal reading cost.

Should you panic? No. Just acknowledge the fact and build processes accordingly. For businesses, it provides reliable identification but raises regulatory risks. For users, it signals the need to clear not only cookies but also HSTS states, profiles, and containers. We’ll show you exactly how.

Real-World Use Cases and Defense Strategies

Our 2025-2026 audits found HSTS tags used by major platforms walking the edge. Not blatant, but via dependent domains and CDN inclusions. Sometimes as fraud protection, sometimes for silent attribution. No outright admissions, but behavioral patterns speak volumes. Marketers value this technique because it works where consent banners cut cookies and users get tired of pop-ups and click “reject all.” Yes, it’s an ethical grey area and not suitable for everyone legally.

Defense is simple in theory but painstaking in practice. Regularly clear HSTS states, use isolated profiles and containers, and preferably limit the domains you trust. Corporations deploy strict policies to block HSTS encoding via suspicious subdomains. For individuals, a quick checklist: clear HSTS databases in browsers, keep separate profiles for sensitive activities, block automatic redirects from dubious sites using extensions like NoRedirect and advanced policy managers. Discipline is key; otherwise, single clearances lose to frequent re-encoding.

ETag Tracking: How "Zombie Cookies" Return Through Cache

How ETag Works and Why It’s Persistent

ETag is a cache validation mechanism. The server sends an ETag hash or unique string; the browser later sends an If-None-Match header to check freshness. If it matches, the server replies 304 Not Modified, saving bandwidth and everyone’s happy. But that "unique string" can also be a user identifier. The file is identical, but each browser receives its own ETag. So your browser automatically returns your ID to the server—even after clearing cookies—because the tag lives in the cache and conditional request logic.

Servers can generate ETags not as pure content hashes, but as pseudo-random signatures linked to users, IPs, user agents, or other context. Then analytics magic happens: matching ETags, request sequences, response timings, and cross-domain resources via CDN. From marketing’s point of view, ETag is handy where stable pseudonyms matter but cookies aren’t usable or consent isn’t given. This method falls into the gray, even black, tracking zones. Yet it’s widespread because it’s so accessible.

Cross-Site Scenarios and Service Workers

In 2026, ETag tracking increasingly pairs with Service Workers and caching strategies. When Service Workers handle caching, they finely control response variants, ETag dynamics, and underlying matches. Add CDNs optimizing performance by serving varied resource versions, and you get persistent "zombie identifiers" that survive regular "clear site data" actions and reappear with static asset updates. Many users believe they’ve wiped everything because cookies vanish, but caches remain—and they’re talkative, to say the least.

Is this scary? Yes, if hidden identification concerns you. But being vulnerable isn’t mandatory. Browsers strengthen protection, limit ETag usage in cross-site contexts, and strive to normalize caches. There’s no universal ban, though, or the web’s efficiency suffers. It all boils down to smart configuration and digital hygiene. And yes, there are effective steps.

How to Defend Yourself Without Paranoia

First rule: you must manage caches selectively. Not just "clear browser data," but selective cache, storage, and Service Workers clearance. Second rule: isolation. Use separate profiles or containers for accounts and workspaces, no overlap. Third rule: anti-trackers and policies limiting If-None-Match and unusual ETags on cross-domain requests. Some browsers and extensions already offer presets to reset ETags on cross-origin calls. Finally, test thoroughly. Simple setups will reveal how your browser handles ETags under various conditions. A month or two of audits show clear impacts in anti-tracker reports and developer consoles.

TLS Session Resumption: Handshake-Level Tracking

Session IDs, Tickets, and 0-RTT Ease Connections but Leave Tracks

TLS session resumption speeds up reconnects. Instead of a full handshake, client and server resume sessions via Session ID or Session Ticket. Faster? Great. But resumption creates a durable link between visits—especially if tickets last long and cover multiple hosts under one operator. TLS 1.3 extends this with 0-RTT, giving instant response but a stable connectivity marker for trackers. Elegant yet ambiguous.

If providers or platforms manage request fronts and session keys, they can correlate repeated visits even with changing IPs. VPNs complicate tracking but don’t break it. TLS-level “memory” persists. It’s subtle and not always conclusive alone, but combined with factors like time, user agent, and request patterns, it offers high-match certainty. That’s why advice like “clear TLS cache,” “terminate sessions,” and “avoid 0-RTT” matters in some cases. We’ll return to practical setups later.

JA3, JA4, and Client Hello Fingerprints

Beyond resumption, TLS ClientHello parameters form fingerprints—collections of supported ciphers, extensions, and value orders—known as JA3, now often JA4 with protocol/version refinements. Not unique to individuals but good at narrowing groups. When paired with Session Tickets and CDN data, correlation works well. Add QUIC’s Connection ID, and clusters get even stronger. So even switching IPs through VPN won’t prevent grouping sessions into unified behavioral “clusters” precise enough for attribution and fraud detection.

Where is this used? Everywhere speed, stability, and bot protection matter. Marketing seldom leverages TLS-level signals directly but large ecosystems share telemetry between subsystems. That’s why privacy isn’t just about "browser cookies," but network metadata collected by content delivery and security infrastructures.

What To Do: Practical Steps

First, lower 0-RTT where ultra-low latency isn’t critical. Some browsers and crypto systems have flags to disable early data. Second, keep browsers and platforms updated to use ECH (Encrypted Client Hello) and other methods hiding handshake details. Third, restart your VPN sessions regularly—don’t keep one chain for hours. It’s not a silver bullet but lowers correlations. Fourth, in sensitive contexts, use isolated systems—even separate virtual machines with unique behavioral profiles. Sounds heavy? Not everyone needs it, and we’re upfront about that.

Why VPNs Don’t Fully Protect Against Advanced Tracking

VPN Encrypts and Masks IP—But What About the Rest?

We love VPNs for their simplicity: click a button, your IP changes, ISPs don’t snoop, and café Wi-Fi isn’t eavesdropping. Wonderful. But, honestly, VPNs don’t hide browser fingerprints, don’t clear HSTS tags, don’t replace cached ETags, and don’t alter behavioral patterns. They operate at the network layer while tracking happens on multiple layers—from network cards and TLS to WebGL and shared fonts. In the end, a VPN is an umbrella when it rains, but if you’re standing knee-deep, the umbrella only helps so much.

We often hear, “But I use multihop and IP rotation.” Great. That helps reduce geo-location accuracy, IP correlations, rough tracking, and regional blocks. Yet fingerprints, caches, and tokens last longer. And if you visit the same sites daily, resolvers, CDNs, and anti-fraud systems quickly recognize the same feature set despite changing IPs. Plus, WebRTC leaks, DNS requests bypassing the tunnel, and TLS quirks from misconfigured clients add complications.

Where VPN Helps and Where It Doesn’t

VPNs protect against traffic interception on insecure networks, bypass geo-restrictions, and reduce basic IP correlations. They hide your real IP from sites unless you reveal it via WebRTC or similar channels. But they don’t defend against browser fingerprints without other measures, don’t clear HSTS or ETag tags without isolation, and don’t stop TLS correlations without session handling. That’s normal. Don’t expect a screwdriver to work like a power drill. Use the right tool for each job.

The takeaway: VPN is your first line of defense. Sometimes your second, if configured well. But privacy in 2026 demands a layered approach where each layer addresses a specific risk class—network, browser, behavior, and organizational habits.

Trust in Providers and Logging Policies

A separate issue is who your VPN provider is, who manages your DNS resolver, and who runs the CDN you connect through. The phrase “no logs” sounds nice but what matters is architecture: RAM disks, independent audits, jurisdiction transparency, key rotation. And this only functions alongside your digital hygiene. Because the most "logless" provider still won’t protect against ETag if your browser keeps sending If-None-Match headers and you log into the same accounts with identical digital fingerprints. It sounds dull, but that’s life.

Comprehensive Protection Against Super Cookies, ETag, and TLS Metrics

Browser Profiles, Containers, and Isolation

Most importantly—separate contexts. One profile for work, another for personal life, and a third for sensitive tasks. Firefox has containers. Chrome and Edge support separate profiles. Safari offers profiles and “private windows,” but we recommend distinct profiles. Think of it as having different pairs of gloves for different jobs—don’t mix dirt from one to another. This isolation limits HSTS states, cached ETags, and Service Workers moving between your online “lives.”

If you manage accounts on many platforms, try the rule “no more than two domains per profile” for critical tasks. This reduces cross-correlation risks via shared resources. Adopt this habit gently but firmly. After two weeks, your brain stops resisting and this behavior becomes second nature. How to clear? A simple checklist is coming up.

Anti-Trackers, Policies, and Fingerprint Normalization

The second layer is browser-based defense. Enable strict tracker blockers and use reputable extensions. Helpful are lists limiting suspicious ETag patterns and normalizing headers. In 2026, many solutions add “time masks” and “size noise.” Not a cure-all, but combined with profiles, very effective. Normalizing fingerprints makes your browser look like many others instead of a unique snowflake. Brave, Firefox, and Safari have advanced here. Chrome addressed part through Privacy Sandbox and own restrictions, but basic protection rarely suffices without extensions.

To avoid confusion, keep a “whitelist” of sites where you need full functionality and consciously allow tracking. Everywhere else, enforce strict rules. After all, we don’t leave our apartment doors wide open just because we don’t want to turn a key.

Clearing HSTS, Caches, and Service Workers

Regular data cleaning isn’t just about cookies. Include clearing HSTS states, caches, and Service Workers in your routine. Weekly or after sensitive sessions. Some browsers hide HSTS clearing deep in settings or internal pages—seek it out, don’t skip it. Also, use disposable profiles wiped after tasks to defeat “zombie tags” that survive local removal and bounce back like nothing happened.

A useful tip: block auto-registration of Service Workers on unfamiliar domains where offline features or caching aren’t important. It’s not always convenient but removes another correlation line where possible.

Tools in 2026 That Actually Work

Browsers with Anti-Fingerprinting and Enhanced Privacy Modes

If you’re not up for deep dives, start with browsers that cut noise out of the box. Brave with aggressive shield policies, Firefox with strict ETP and containers, Safari with smart ITP well integrated into Apple’s ecosystem. No browser is perfect, and corporate environments often balance Chrome and Edge for compatibility. Then use strict modes, add extensions, and keep updating. In 2026, updates aren’t cosmetic—they bring ECH, improved isolation, and better policy control.

One more thing: “one browser for everything” is outdated. Create profiles for specific tasks, enable anti-fingerprinting where possible, and relax rules where full functionality is essential. Don’t fear mixing it up. This isn’t hacking, it’s smart use.

Next-Gen Networks: ECH, MASQUE, Multihop

The network layer evolved too. ECH (Encrypted Client Hello) hides TLS handshake details to thwart fingerprinting and SNI snooping. MASQUE and CONNECT-UDP allow flexible obfuscation over QUIC apps, proxying traffic with fewer metadata leaks. Multihop and port rotation complicate intermediaries’ correlation. But watch your DNS setup—if it leaks outside the tunnel, benefits shrink. Use DoH or DoQ under client or trusted providers’ control, not just marketing promises.

Don’t forget WebRTC. Even in 2026, disabling uncontrolled ICE candidates is a must if you worry about revealing your real IP. One careless media permission in your browser and your “masked” presence is exposed. Fix this with simple browser settings and testing via a couple of tools.

DIY Solutions and Leak Minimization

Some users opt for self-hosted tools: reverse proxies, own DNS resolvers, router-level filters. This boosts control and transparency, though it demands time and effort but grants independence from 3rd-party policies. For businesses, this becomes standard: perimeter tracker filtering, cache policies, centralized clearing, and Service Worker control. Fewer random leaks break your threat model and spoil analytics.

But never forget the human factor. One wrong click, one all-purpose profile, and weeks of careful cache rules go down the drain. Discipline beats occasional “hard” cleans every time.

Practical Scenarios and Checklists

Marketing and Web Analytics: Playing Fair

If you manage analytics, you face different challenges. Cookies are limited, consent is mandatory, and attribution suffers. What to do? Stick to a minimal set of signals. Use aggregated reports, identifier-free attribution, and built-in ad platform APIs like Attribution Reporting in browser ecosystems. Don’t exploit HSTS or ETags for hidden tags—it strains legal standing and reputation. Build analytics that survive future bans. It’s cheaper and more sustainable than gray shortcuts.

Work transparently with Consent Mode, respect refusals, and don’t hide tracking in caches. First, such practices are now detected and penalized. Second, savvy users clear those tags and break your model anyway. Third, brands lose trust. The short-term gain isn’t worth the long haul cost.

Corporate Security and Insight Protection

For companies, the priority is different: prevent leakage of contextual traces and protect accounts. The policy is simple: isolated profiles per department, centralized cache and HSTS clearing, limit external Service Workers, strict browser rules, and timely updates. Filter trackers and normalize headers at the network edge. Critical roles get dedicated devices or VMs with frozen fingerprints and separate routes via different providers. Don’t shove everyone into Tor—expensive, inconvenient, and not always justified. Most importantly—regular policy reviews. Quarterly audits and attack simulation, including “honest” tracking methods, reveal what really persists in the wild.

Journalists, Activists, and Sensitive Roles

The stakes are higher here. You need deanonymization resistance and long-term surveillance resilience. Enable multi-layer isolation of profiles and devices. Different profiles for different identities, separate network exits (Tor for the ultra-critical, trusted multihop VPN for daily use), disable 0-RTT, strictly control WebRTC. Avoid a single “main” account that will expose all your activity. Clean caches and HSTS meticulously, or better yet, use disposable session profiles destroyed after task completion. It’s inconvenient but exponentially reduces risk.

Add behavioral masking too. Vary visit patterns, avoid unique plug-in and font combos, normalize screen resolutions in virtual environments. Don’t chase “perfect” anonymity—it doesn’t exist. But lowering correlation is both possible and wise.

Myths and Realities About Privacy

The Myth of Complete Anonymity Being Available to Everyone

The truth: full anonymity is expensive. It requires closed networks, special protocols, strict discipline, or a combination. Most people don’t need that level of strictness—they want reasonable privacy without sacrificing usability. So don’t aim to “disappear from the internet.” Aim instead to “minimize exposure and complicate correlation.” That’s realistic, fast, and affordable.

The most dangerous thing is illusion. There’s no one “magic” tool that “solves everything.” Each layer needs attention and ongoing routine. That’s how effects add up and show results. And yes, buying another “super VPN” instead of setting up profiles is like treating a cold with expensive vitamins without sleeping or drinking water. Not effective.

The Myth That Consent Banners Either Save or Kill It All

Consent is legally important, but it doesn’t block caches, HSTS states, or network correlations. Privacy-conscious companies pair cache control and isolation with consent modes. Privacy-aware users don’t rely on banners—they manage profiles and clear traces regularly. At the end of the day, banners are contracts, not hygiene automation.

Moreover, many banners are set up so you “agree” without understanding depth. Apply critical thinking, use browsers that intelligently cut trackers, and don’t hesitate to “reject all” where it fits you. Your data is your responsibility.

The Myth That GDPR or Local Laws Will Solve Everything

Regulations help. They set frameworks, punish abuses, and discipline markets. But they don’t replace technology. Tracking evolves faster than amendments pass. Winners are those who build processes now, not wait for mandates. For businesses—privacy by design; for users—privacy by routine. Laws push only the worst actors.

There’s a flip side: laws push platforms toward identifier-free solutions with logic split between cache, browser, and network. It’s a “shadow valley” situation—legally sound but still very informative. Hence our talk about HSTS, ETag, and TLS.

Where Tracking Is Headed in 2026–2028

Privacy Sandbox, Attribution, and the End of Third-Party Cookies

For the third year running, browsers shut doors on third-party cookies. Instead, Privacy Sandbox, identifier-free attribution, and on-device approaches grow. This reduces crude tracking but won’t kill it. Tracking becomes statistical, aggregated, and harder to explain. Marketing models flourish that compute interests client-side, sending only generic signals out. Is this good or bad? Depends on who controls implementation and process transparency.

For privacy protection, it’s a double-edged sword. Fewer clear IDs, but more protocol intricacies enabling correlation. So your “baseline” toolkit stays relevant: profiles, caches, HSTS, ETag, and network metadata remain key nodes.

On-Device ML and Predictive Identification

Another trend is shifting personalization and anti-fraud logic onto devices. Phones and laptops aren’t just “clients”—they’re computing participants. This benefits privacy if models don’t emit explicit “hints” describing you uniquely. Examples include predictive grouping by navigation patterns, reaction times, subtle UI lags. Such signals are hard to fake but easy to use for “shadow” IDs. The community pushes for transparency and control; meanwhile, watch app permissions and policies closely.

For businesses, this poses challenges. On-device models are tough to maintain, and regulators demand explainability. Those who balance this win. For users, the advice stays the same: choose platforms with clear settings that don’t hide controls deep in menus.

QUIC Everywhere, ECH by Default, and Less Visible Metadata

QUIC has become standard for major platforms. Good for speed and reliability. From a tracking view, it changes the game. Connection IDs, connection migration quirks, and encryption details simultaneously make passive intermediary tracking harder but enable new stable correlations for content providers. ECH is rolling out as default—great news. Less visible metadata along the route means fewer third-party spying chances. But trackers won’t vanish—they’ll shift closer to client and server, where app and browser owners control data.

Does this mean the battle is lost? No. It means the toolkit evolves. And we evolve with it.

30-Day Protection Roadmap

Days 1–7: Basic Hygiene

Start with inventory. How many profiles in your browsers? Which extensions? Which VPNs and proxies? DNS resolution setups? Create at least two profiles—personal and work. Enable strict tracker protection. Disable WebRTC leaks and 0-RTT where latency isn’t critical. Clear caches, HSTS, and Service Workers fully every couple of days in at least one profile. Note any difficulties. We’re not superheroes, just people who want a bit of order.

Also update all browsers and check for ECH availability. Turn it on if possible. Configure DoH or DoQ under your client’s control. Don’t forget to verify that traffic flows through the tunnel and DNS doesn’t leak.

Days 8–21: Isolation and Automation

Add a third “sensitive” profile for banking, healthcare, and private accounts. Use tighter cache isolation and disable unneeded extensions. Set up automated scripts or scheduled tasks for regular cache and HSTS clearing. For corporate devices, sync policies with IT security. Check approved domain lists for Service Workers and relaxed rules.

At the same time, commit to the “one profile—one task type” discipline. Mixing increases linked tag risk. Don’t beat yourself up for slips—just get back on track. Privacy isn’t a test; it’s a process.

Days 22–30: Fine Tuning and Verification

Wrap up with a mini-audit. Review anti-tracker logs, scan ETag behavior, test fingerprint changes across profiles. If you have high demands, try combining Tor for critical tasks and VPN for daily work. Enable resolver rotation and periodic session restarts. Evaluate what really helps and what only hinders. Keep the best with minimal pain, discard the rest.

After a month, you’ll have a resilient, imperfect but practical protection setup—no overkill or magic fixes.

Conclusion: What to Remember

Key Takeaways in One Place

HSTS super cookies, ETag, and TLS resumption aren’t horror stories—they’re 2026’s routine. They exist below cookie level, carrying identifiers between sessions. VPN helps but alone doesn’t solve ID issues. Protection builds through layers—profile isolation, cache and HSTS control, fingerprint normalization, careful network config with ECH, DoH, and no WebRTC leaks. Add discipline and simple habits, and your digital footprint becomes much harder to track. The goal isn’t perfection but correlation difficulty.

Please, no extremes. Easy, repeatable steps beat rare heroic efforts. We don’t have to outrun all trackers—just stop being the easiest target.

What to Read and Improve Next

Keep up with browser updates, watch for default ECH and anti-fingerprinting improvements. Periodically check your VPN and resolver policies. Master containers and profiles. And remember your goals. If you want privacy just “above average,” don’t dig tunnels that won’t pay off. If you need maximum protection—prepare processes and tools, not just software.

FAQ

Do HSTS Super Cookies Really Exist or Is It a Myth?

They do exist. They aren’t “cookies” technically but persistent markers in HSTS policies encoded via subdomains and durations. Hard to clear by usual means since they live separately from cookies and localStorage. The battle is simple in theory but requires discipline: regular HSTS clearing, profile isolation, blocking suspicious redirects and resources. Corporations apply policies banning such tricks. For individuals, a solid routine and occasional “post-mission” cleanups suffice.

Can ETag Tracking Be Blocked Without Major Performance Loss?

Partially. Banning ETag outright hurts cache efficiency and inflates traffic. But compromises are possible: strict cross-domain request policies, ETag normalization, clearing If-None-Match in suspect contexts, and regular cache cleaning. Some extensions and browser modes already minimize risk without killing caching. Just pick the right lists and remember to clear Service Workers—otherwise “zombie tags” return.

Does Disabling 0-RTT in TLS Really Help or Is It Just Theory?

It helps in particular cases where minimizing stable session links matters. 0-RTT speeds things up but makes session resumption easier to track. If milliseconds aren’t critical, disabling 0-RTT lowers correlation. That said, it’s no “magic bullet.” Effects materialize combined with other measures—profile isolation, cache clearing, ECH, and WebRTC/DNS discipline.

VPN or Tor: Which Is Better for Privacy?

Depends on your goals. Tor offers higher anonymity but is slower and needs cautious use. VPNs are convenient, faster, and good for everyday tasks but don’t hide fingerprints or remove HSTS/ETag tags. Often it makes sense to use both situationally: Tor for critical needs, VPN daily, plus profile isolation and regular clearing. Don’t overcomplicate. Start with basic hygiene, then add specialized tools.

Is One “Right” Browser Enough?

No. One browser for everything creates correlation points. Better to have at least two profiles, ideally three by task type. Add anti-trackers, enable strict modes where compatibility isn’t crucial, separate Service Workers. Update browsers for ECH and better policies. And remember, software alone won’t do it. Habits matter just as much.

Can You Live Without Cookies But Still Have Comfortable Analytics?

Yes, by shifting to aggregated attribution and solving tasks without hidden identifiers. Modern platforms offer reports and APIs that work without third-party cookies. Accuracy drops but legal stability rises and users are happier. Gray methods via caches and HSTS offer short-term gains but long-term risks. Smart marketing understands this and builds "privacy by design."

How Quickly Can You See Results From These Recommendations?

Often within 1-2 weeks. After splitting profiles and cleaning caches regularly, stable correlations drop and anti-trackers detect clearly fewer matches. Add network measures—ECH, DoH, WebRTC control—and you’ll notice “returning” sessions less often grouped. This shows in softer bans and less pushy personalization. The main thing: don’t stop after initial success. Privacy loves routine.
