Tracking Protection Settings
Enhanced Tracking Protection (Firefox): Firefox's most impactful privacy feature. Set to Strict mode (Settings → Privacy and Security → Enhanced Tracking Protection → Strict). This blocks social media trackers, cross-site tracking cookies, cryptominers, fingerprinters, and tracking content in all windows. Strict mode occasionally breaks site functionality — if a site misbehaves, temporarily disable protection for that site using the shield icon in the address bar.
Tracking Prevention (Edge): Edge offers Balanced (default) and Strict tracking prevention. Strict blocks a wider set of trackers and provides protection closer to Firefox Strict mode. Enable via Settings → Privacy, Search, and Services → Tracking Prevention → Strict.
Chrome: Chrome does not have meaningful built-in tracking protection as of 2026. Google's Privacy Sandbox is an advertising technology replacement, not a privacy protection. Use uBlock Origin extension for Chrome to add tracker blocking.
Cookie Settings
Third-party cookies allow advertisers and trackers to follow you across different websites. All major browsers now block or restrict third-party cookies by default or provide settings to do so. In Firefox, Strict tracking protection blocks third-party cookies. In Chrome, block third-party cookies in Settings → Privacy and Security → Third-party cookies. In Safari, third-party cookies are blocked by default.
First-party cookies (cookies set by the site you are visiting) are necessary for login sessions and preferences — blocking all cookies breaks most websites. The target is third-party cookies only. Firefox Total Cookie Protection (enabled in Strict mode) takes a stronger approach: it isolates each site's cookies in a separate jar so trackers cannot link your activity across sites even using first-party cookies.
DNS over HTTPS in the Browser
Enable DNS over HTTPS in your browser to encrypt domain name lookups for that browser's traffic. In Firefox: Settings → Privacy and Security → DNS over HTTPS → select Default Protection or Increased Protection. Choose a provider (Cloudflare, NextDNS, or your own DoH resolver). In Chrome: Settings → Privacy and Security → Security → Use secure DNS → With a provider of your choice. In Edge: Settings → Privacy, Search, and Services → Use secure DNS.
Browser-level DoH protects only that browser's DNS queries. Other apps on your machine still use the OS's DNS. For whole-device protection, configure DoH at the OS level (Windows 11) or on your router using AdGuard Home.
Fingerprinting Resistance
Browser fingerprinting tracks you using a combination of browser characteristics: screen resolution, installed fonts, timezone, language settings, GPU renderer, and dozens of other signals that together identify your specific browser without cookies. Fingerprinting bypasses cookie clearing and private mode.
Firefox has built-in fingerprinting protection (enabled in Strict tracking protection mode) that randomizes or limits access to fingerprintable APIs. Brave Browser includes advanced fingerprinting protection by default. Tor Browser provides the strongest fingerprinting resistance by making all Tor users appear identical. Chrome has limited fingerprinting protection — extensions like CanvasBlocker help but are not a complete solution.

Frequently Asked Questions
Which browser is best for privacy?
Firefox with Strict tracking protection and uBlock Origin provides excellent privacy without sacrificing compatibility. Brave offers strong built-in privacy protection for users who prefer a Chromium-based browser. Tor Browser provides the highest privacy at the cost of speed. Avoid Chrome if privacy is a priority — it is built by an advertising company with significant data collection built in.
Does uBlock Origin work differently in Chrome vs Firefox?
Yes. Google's Manifest V3 (MV3) extension API, now required for Chrome extensions, limits the capabilities of content blockers. uBlock Origin on Chrome (using MV3) has reduced blocking capabilities compared to the Firefox version (which still uses the more capable MV2 API). Firefox's version of uBlock Origin is more effective — another reason Firefox is preferred for privacy-focused users.
Should I use a privacy-focused search engine?
For browser privacy, your search engine affects what your searches reveal about you. Google and Bing log searches associated with your account and IP. DuckDuckGo, Kagi, Brave Search, and Startpage do not profile users by search history. Use a privacy-respecting search engine alongside browser privacy settings for comprehensive protection.
Does HTTPS mean a website is safe?
HTTPS means the connection between your browser and the website is encrypted — no one on the network can read the content. It does not mean the website itself is trustworthy or that it does not collect your data. Phishing sites, malware distribution sites, and data-harvesting sites all commonly use HTTPS. HTTPS is necessary but not sufficient for safety.
