Launch Firefox, manually check for latest update by going to settings > Help > About Firefox. However the manual update keep showing update failed. Other than Mozilla config file, can we use GPO to configure auto update for Firefox browser?

If you have trouble with the upgrade, use this link; http://www.mozilla.org/en-US/firefox/all/

Can you go to about:config and set app.update.log to true on one of the failing machines and then use the Javascript console (Ctrl+Shift+J) to see if there is information as to why the update failed?

And yes, you can use GPO to force update, but that error will probably still happen
