I downloaded the updates, now Firefox won't load as it says I must close the other sites to install the updates, which I don't have. I can't disinstall and reload as the program won't close.

The automatic update came up and I downloaded them. When it came to reboot the computer a message comes up, can't install the updates, make sure all other firefox sited are closed. As there are no other firefox sites on my computer I click OK and the updates try to load ad infinitum. When I try to disinstall the program to download it again , I can't as the program updates won't install so I can't disinstall. What can I do to cancel the updates or re load the program?

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can skip the step to create a new profile, that is not necessary for this issue.
