This article describes how to install a previous version of Firefox, a process also known as "downgrading". For instructions on how to install a newer version, see Update Firefox to the latest release.
Installing a previous version doesn't fix most problems
Problems after upgrading Firefox are generally not caused by the new version itself, but rather the upgrade process. Installing a previous version will not help for most problems, such as:
- Can't access websites anymore
- "Firefox can't connect securely..." error
- Re-enable add-ons that were disabled when updating Firefox
Other problems can be solved by creating a new profile.
