How to downgrade Firefox version?

Pridané

Is there an easy way to downgrade from Firefox 49.0.1 to 44? Or, do I need to remove Firefox and download again? I've been reading that the issues I'm having with the Selenium firefox webdriver work better with the version 44.

We don't recommend running outdated Firefox versions, but it is certainly possible. All previous versions of Firefox are archived on the Mozilla FTP server. You can just download the installer and run it. It should install over top the current version, while preserving your user data.

Warning: Old versions of Firefox may be vulnerable. Use with caution and at your own risk.
Note: To prevent data loss in the event of an error, it is recommended that you backup your Firefox profile(s) before downgrading.
