Want to uninstall Nightly from my Windows computer and revert to Firefox, which I have used for many years. Message when I attempted to download Firefox is that I have the latest version already.

The Help menu in Firefox refers only to Nightly Help, About etc. Does this mean that Nightly and Firefox are inseparable and that downloading Firefox again would give me Nightly again?

I have Nightly showing in Control Panel programs list, so assume can be removed via Control Panel.

Could anyone confirm that the latest download does not include Nightly? Or, if it does, how can it be excluded? Also, in downloading/installing latest Firefox, is there provision for retaining bookmarks, settings etc? Thank you very much, Helen

Hello Helen,

the latest stable firefox version is the 31.1.1 and you can download it from the next link (full installer) : https://www.mozilla.org/en-US/firefox/all/

Firefox nightly is a build for testing only, all new things first tested in nightly.

yes you can remove firefox from Control panel, but it is better to go for a clean-reinstall, this means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from the next link (all languages-full intaller)https://www.mozilla.org/firefox/all/ and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (or open the Firefox menu New Fx Menu and click the close button Close 29).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default in Windows:
  • C:\Program Files\Mozilla Firefox
  • C:\Program Files (x86)\Mozilla Firefox

Now, go ahead and reinstall Firefox:

  • Double-click the downloaded installation file and go through the steps of the installation wizard.
  • Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.


Thank you.
