Firefox stuck in endless loop asking to restart to finish previous update but does nothing. Can uninstall or install newer version over it. I believe the setup files were erased before reboot by another installer. How do i fix this?

Anything i try related to firefix gets "Your computer must be restarted to complete a previous upgrade of Firefox" I have tried rebooting no luck, i have tired uninstalling from add remove programs or installing 4.0 over it. At the time I was try to upgrade from 3.0 to 3.6.15. I tried searching for the xpicleanup.dat file but no luck there.

I had the same problem. I deleted a file 'firefox.exe.moz-upgrade' from 'C:\Program Files\Mozilla Firefox' directory and the installation / upgrade of Firefox went on fine

Thank you. That worked.

I was having the same problem, so I deleted 'firefox.exe.moz-upgrade' from 'C:\Program Files\Mozilla Firefox' directory, as recommended. Now it no longer says it needs a restart to complete a previous installation. It says it needs a restart to complete a previous uninstall. What do I do now? Help!

Delete the entire 'Mozilla Firefox' directory then proceed to download the newest version of FireFox from http://www.mozilla.org/

Re-install FireFox.
