Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

This fix worked for me. Thank You. Windows 7 option didn't appear on this Vista Desktop. XP Service Pack 2 was highest MS OS, so I used that. It worked. Again, Thank You.

1. right click firefox - this means to hoover your mouse over the firefox icon on your desktop, and then click the right mouse button.

   2. click properties - this means to hoover your mouse over properties (usually the entry at the bottom of the menu that will pop up after completing step 1 of this article), and press/click the left mouse button.
   3. click compatibility tab - this means to hoover your mouse over compatibility tab, and left click it. You'll find compatibility tab near the top of the Mozilla Firefox Properties Pop-Up Box, in the center.
   4. check "Run this program in compatability mode for:" - This means to left click your mouse while hoovering the mouse over the little square check box, that is to the left of "Run this program in compatibility mode for:" Then, left click the drop down arrow on the far right end of the drop down box immediately below that check box. and click windows 7 if available, or XP service pack 2.
   5. on dropdown choose Windows 7.
   6. click ok or apply.  Do remember to click apply, and then Ok at the bottom of the popup box, or this will not work. Good Luck.
