If there is a problem with a Firefox, 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.

Installing a previous version doesn't fix most problems
Problems with an update are generally not caused by the new version of Firefox, but rather the update process. Installing a previous version will not help in most cases. Instead, see:
- How to fix the Update Failed error message when updating Firefox
- Fix problems connecting to websites after updating Firefox
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 Such software may not be essential for your security, but if outdated, it may interfere with the use of Firefox, or cause Firefox to crash.
I still want to downgrade — where can I get the previous version?

Downgrade alternatives
Instead of downgrading to an older, insecure version of Firefox and changing your update settings, you should consider these alternatives:
Install Firefox Extended Support Release. Firefox Extended Support Release (ESR) is an official version of Firefox developed for large organizations like universities and businesses. Firefox ESR does not come with the latest features but it has the latest security and stability fixes. For more information, see the article Switch to Firefox Extended Support Release (ESR) for personal use.
Use the latest version of another browser. If the current Firefox version is not to your liking or just not working right now, there are alternative browsers that you can use to browse the web.
