In their own words
LibreWolf
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.
Mozilla Firefox
Mozilla Firefox is a free, open-source web browser that uses the Gecko engine. It is available on Windows, macOS, Linux, iOS, Android, and as a browser extension, and its download page lists availability in more than 90 languages. Standard tracking protection and built-in ad blocking are included. Total Cookie Protection isolates cookies so they cannot follow users between websites, while Tab Groups organize open tabs by project, mood, or task. A Mozilla account can sync bookmarks, passwords, and open tabs across devices. Firefox also offers access to multiple AI chatbots in one place, letting users choose whether to use them. Thousands of free extensions are available through addons.mozilla.org. Mozilla’s privacy notice says browsing history, form data, temporary files, and cookies are processed on the device unless stated otherwise. Automated translation and PDF alt-text suggestions use downloaded language models locally; Firefox says those features do not send page content, PDFs, images, or tab URLs to Mozilla. Firefox is listed at free.
