Other Versions of Firefox

Firefox is available in many languages for Windows, Mac, and Linux, in both 32-bit and 64-bit. You can see all of these downloads on one page on Mozilla's site.

Firefox is also available for Android devices from the Google Play store and for Apple devices from the iOS App Store.

Pre-release versions of Firefox are also available for download.

A number of download sites offer the latest version of Firefox, but some of these sites bundle additional, probably unwanted, software with their download of the browser. Save yourself the trouble and use Mozilla's website to download Firefox.
