Warning: Firefox now includes downgrade protection to prevent corruption of user profile data. If you install an older version, you'll be prompted to create a new Firefox profile.

Opera can be your new browser, with all of your bookmarks, passwords and autofill data, in just a couple of clicks. When you change browsers to Opera, you will automatically be prompted to import whatever data you want from your old browser. If you are already using Opera, you can import everything. The folders I had in Opera were not shown in firefox and loads of bookmarks just dumped on the top level Tied this three times now with different versions of Firefox (also from different versions of Opera) Was hoping to move over to firefox for good but if this does not work am stuck using Opera! Opera and Firefox are two of the oldest active web browsers and have both changed dramatically over their long lifespans. Throughout their existence, they have both occupied a niche corner of the. The Firefox browser also gives users the ability to sign up for a free Firefox Account. Having a Firefox account is the key to unlocking syncing across devices, plus you get the added benefit of products like Firefox Monitor which monitors your email addresses and alerts you if any of your information has been involved in any known data breaches.

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.

Firefox is for everyone Available in over 90 languages, and compatible with Windows, Mac and Linux machines, Firefox works no matter what you’re using or where you are. Make sure your operating system is up to date for the best experience.

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:

Firefox
Note: Other problems can be solved with the Refresh Firefox feature. It restores Firefox to its default state while saving your essential information.

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.

If you still want to downgrade, you can visit Mozilla's directory of older Firefox versions using the links below. Please note, however, that using older versions can make Firefox insecure and more vulnerable to attacks and scams. We recommend that you always use the newest version of Firefox.
