In their own words
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.
Mullvad Browser
Mullvad Browser is a free, open-source browser designed to reduce tracking and browser fingerprinting. It uses the Gecko engine and runs on supported versions of Linux, macOS and Windows; the Windows version requires Windows 10 or later and a 64-bit system. Fingerprinting protection is intended to make users appear more similar to one another, and uBlock Origin is included to block third-party trackers. The browser also includes ad blocking. Private mode is enabled by default, so cookies, cache and history are not saved between sessions, and a reset button starts a clean session in one click. Mullvad says it has removed browser telemetry. The browser can connect with or without a VPN, but it does not use the Tor Network; it was developed in collaboration with the Tor Project. Cross-device sync is not available. Mullvad says it does not earn money from the browser and instead earns income from its VPN service. Support questions can be sent to [email protected].
