Downgrading usually doesn't solve Firefox problems. This article gives you links to old versions of Firefox and provides some alternatives to downgrading.

{warning}'''Warning:''' [[Dedicated profiles per Firefox installation|Firefox now uses separate profiles for each installation]]. If you install an older version of Firefox, you'll be prompted to create a new [[Profiles - Where Firefox stores your bookmarks, passwords and other user data|profile]] to prevent data corruption. [[Dedicated profiles per Firefox installation#w_what-happens-to-my-profile-if-i-downgrade-to-a-previous-version-of-firefox|Learn more]].{/warning} Often when there is a problem with a Firefox update, people look for a way to go back to the previous version. 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. __TOC__ = 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: [[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 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 Such software may not be essential for your security, but if outdated, it may interfere with the use of Firefox, or cause Firefox to crash. {/for} = 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 not recommended that you use anything but the latest version. {warning}'''Warning:''' Using old versions of Firefox poses a significant security risk.{/warning} {for =fx60} {for win}
