Initially ff was running slow and ie would not load so I uninstalled ff ( control panel only) then I did a system restore (windows 7). Ie would not load ( no proxy server error) and received ff error couldn't load xpcom.. No internet service now. Can't even uninstall ff from control panel. It is there under programs but when I click to uninstall nothing happens. I really need Internet service, please help.

Hello Usnret26, try to boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) and then see if that allows to uninstall firefox.

Then go for a clean re-install, this means you remove Firefox program files and then reinstall Firefox. Delete the Firefox installation folder, which is located in one of these locations, by default on Windows:

  • C:\Program Files\Mozilla Firefox
  • C:\Program Files (x86)\Mozilla Firefox

then

  1. Download, with another browser, the latest Desktop version of Firefox from the next full installer : https://www.mozilla.org/firefox/all/ and save the setup file to your computer.
  2. Double-click the downloaded installation file and go through the steps of the installation wizard.
  3. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back to say if this helped you!

Thank you.
