Release notes for each version of Firefox. Firefox Browser for Desktop. Get the browser that respects your privacy automatically. Available in over 90 languages, and compatible with Windows, Mac and Linux machines, Firefox works no matter what you’re using or where you are.

If there is a problem with a Firefox version, most people will try to revert Firefox back to the way it was before and downgrade it, but we do not recommend this action. Downgrading Firefox leaves a user more vulnerable to attacks and, on most occasions, doesn't fix the problem that occurred while updating. This article gives you some alternatives to downgrading and links to old versions of Firefox, if you do choose to downgrade.

Note: Other problems can be solved with the Refresh Firefox feature. It restores Firefox to its default state while saving your essential information.

Ensure all security and security-related software is fully updated. Some security software will need to be upgraded to a new version for each Firefox version update.

Optional software bundled with security software may also need updating. Such software may not be essential for your security, but if outdated, it may interfere with the use of Firefox, or cause Firefox to crash.

If you want to downgrade, you can visit Mozilla's directory of older Firefox versions using the link below. Please note, however, that using older versions of Firefox can be harmful and that we recommend you use the newest version of Firefox.
Warning: Old Firefox versions pose a significant security risk.
