LibreWolf vs Tor Browser

LibreWolf is an independent Firefox-based browser for people who want privacy and security settings applied by default. It includes uBlock Origin with custom filter lists and strict Tracking Protection, while Resist Fingerprinting is enabled and WebGL is disabled. On closing the browser, it removes cookies and site data; Total Cookie Protection is also enabled. HTTPS-only mode and stricter TLS/SSL negotiation rules add further security controls. DuckDuckGo and Searx are among its listed search providers. LibreWolf says it disables telemetry, does not collect data, and lacks the infrastructure to do so. It is free and open source for Linux, macOS, and Windows. Updates usually follow a stable Firefox release within three days, but the browser has no automatic update capability. DRM playback is off by default but can be enabled in settings. Its built-in password manager is disabled, so the project suggests using another option.

Tor Browser routes its own web traffic through the Tor network to help hide a user's real IP address and resist tracking, surveillance, and censorship. Based on Mozilla Firefox ESR, it adds measures such as letterboxing, user-agent spoofing, and first-party isolation to make browser fingerprinting harder. Connections to different websites use different Tor circuits, while connections to the same website address use the same circuit. HTTPS-Only Mode upgrades connections to HTTPS where possible. Standard, Safer, and Safest security levels restrict browser features to varying degrees, which can cause some pages to work improperly. The browser can access onion services, and users in censored regions can configure bridges during setup. It is free, open-source software for Android, Linux, macOS, and Windows. Only Tor Browser traffic goes through Tor; other applications on the device are not automatically protected. The Tor Project recommends verifying download signatures and strongly discourages extra browser add-ons because they can affect privacy, security, or functionality.
