Downgrading to a previous Firefox version doesn't solve most problems. This article links to older versions and provides some alternatives.

{warning}'''Warning:''' Firefox now includes [[Dedicated profiles per Firefox installation#w_what-happens-to-my-profile-if-i-downgrade-to-a-previous-version-of-firefox|downgrade protection]] to prevent corruption of [[Profiles - Where Firefox stores your bookmarks, passwords and other user data|user profile data]]. If you install an older version, you'll be prompted to create a new Firefox profile.{/warning} 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. __TOC__ = Unwanted features in the new Firefox version = If you dislike new features in the latest version of Firefox, your first reaction might be to go back to the previous version. Rather than downgrading, try getting used to the new features or ask a question on the support forum, to see if there is a workaround or a way to restore the old behavior without downgrading Firefox. See [[Get community support]]. = Installing a previous version doesn't fix most problems= 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: [[Template:UpdateProblems]] {note}'''Note:''' Other problems can be solved with the [[Refresh Firefox - reset add-ons and settings|Refresh Firefox feature]]. It restores Firefox to its default state while saving your essential information.{/note} {for win} 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 Such software may not be essential for your security but, if outdated, may interfere with the use of Firefox or cause Firefox to crash. {/for} = I still want to downgrade — where can I get the previous version? = 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. {warning}'''Warning:''' Older Firefox versions pose a significant security risk.{/warning} {for =fx91} {for win}
