If there is a problem with a new version of Firefox, some people may want to downgrade Firefox to a previous version but we do not recommend this. The latest Firefox version includes security updates so downgrading to an older version leaves you more vulnerable to attacks and usually doesn't fix the problem. This article gives you some alternatives to downgrading and links to older versions of Firefox if you do choose to downgrade.
