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.
