Download them all firefox version

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. Problems with an update are usually not caused by the new version of Firefox, but rather the update process.

In most cases, installing a previous version will not help. Instead, see:. Ensure all security and security-related software is fully updated. Some security software will need to be upgraded to a new version so that it is compatible with each Firefox version update. Optional software bundled with security software also may need updating.

Such software may not be essential for your security but, if outdated, may interfere with the use of Firefox or cause Firefox to crash. In the Menu bar at the top of the screen, click Firefox and select Preferences. Click the menu button and select Options Preferences. Which version would you like?
