I just posted this question and can't figure out how to reply to the post. Mozilla is starting automatically in windows 8 when I start my computer. I HAVE TRIED TO RUN MSCONFIG already!!! When I typed in msconfig to run, I clicked on startup tab. The message I got was that this process is handled in the task manager and there was no options other then to open task manager. I opened task manager and went to the startup tab to uncheck Mozilla but its not listed as being an automatic startup program. WHAT DO I DO NOW????

Hello,

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default: (Note that you are not deleting your profile folder which contains bookmarks, history etc.)
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back to see if this helped you!

Thank you.
