That usually doesn't solve the problem and will make your computer and personal information vulnerable to attack. 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:

- 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 Such software may not be essential for your security, but if outdated, it may interfere with the use of Firefox, or cause Firefox to crash.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?Although Mozilla has a website with old versions of Firefox for testing purposes, it is recommended that you only use the latest version.
