Cannot Uninstall Firefox


I tried to uninstall Firefox today and it will not work.

I have Windows XP and so tried Add or Remove Programs in the Control Panel. My computer does not respond at all.

I also tried running C:\Program Files\Mozilla Firefox\uninstall\helper.exe. This also produces no response.

I can open the folder C:\Program Files\Mozilla Firefox, open the uninstall folder and try and open the helper program. Again, my computer does not respond.

I notice that this question has been raised numerous times on this forum before but, as far as I can see, no one has ever answered it.

Any help would be very much appreciated.

Thank you.

See this line in that article for manual removal instructions. Even if the uninstall fails, as it may in some cases, continue on with the rest of the uninstall instructions.
