Browsers

Seven browsers by engine, out-of-the-box privacy and how far you can configure them.

Browsers
BrowserEnginePrivacy by defaultCustomisabilityMy take
FirefoxGecko (Mozilla)Good with hardeningExcellentBest all-rounder. Open source, independent engine, massive extension support. Requires configuration to reach its potential.
BraveChromium (Google)Very good out of boxGoodBest zero-config option. Built-in ad and tracker blocking, fingerprint randomisation. Chromium base is a minor concern; Brave's additions are legitimate.
LibreWolfGecko (Firefox fork)Excellent out of boxGoodFirefox pre-hardened. Ideal if you want Firefox-level privacy without doing the configuration yourself.
Mullvad BrowserGecko (Firefox fork)Excellent, Tor-modeLimitedBuilt with the Tor Project. Maximises fingerprint uniformity — everyone using it looks the same. Prioritises anti-fingerprinting over convenience.
ChromiumChromiumModerateGoodGoogle Chrome without the Google. Better than Chrome, not as good as the options above. Acceptable if you need Chromium-specific compatibility.
ChromeChromium (Google)PoorLimitedGoogle's product. Every page you visit is a data point in Google's profile of you. Do not use as your primary browser.
SafariWebKit (Apple)DecentPoorBetter than Chrome on privacy. Apple's ITP (Intelligent Tracking Prevention) is genuinely effective. No extension ecosystem worth noting. Fine on Apple devices if you won't switch.
