My Firefox wasn't working, so I thought I would simply delete it and reinstall. I couldn't get it to uninstall. I used Revo Uninstall and now can't reinstall.

Do Not remove the profiles folder.

Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder.

After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.
