Warning: Firefox now includes downgrade protection to prevent corruption of user profile data. If you install an older version, you'll be prompted to create a new Firefox profile.

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.
