I used FF for years. Yesterday I couldn't open. The clock lights up a second then turns off. IE works OK. I uninstalled and reinstalled FF

I uninstalled FF and reinstalled with the same results. IE and Chrome work fine. It is something that just started yesterday afternoon. Can you help me?

Hello

Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that disables some settings and disables most Add-ons (extensions and themes).

(If you are using an additional theme, place you in default theme.)

If Firefox is open, you can restart in Mode without failure of Firefox in the Help menu by clicking on the restart with the disabled... modules menu item:

If Firefox is not running, you can start Firefox in Mode safe mode as follows:

  • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
  • On Mac: Hold the option key during the startup of Firefox.
  • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
    (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

Once you get the pop-up, simply select "" boot mode safe. "

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. Please follow the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

When find you what is causing your problems, please let us know. This might help others with the same problem.

Thank you.
