I have discovered that even opening the context menu, without even selecting an item causes this to happen. I have uninstalled and reinstalled the software. Here is my system info:

Hello,

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.

Thank you, Waka_Flocka_Flame. Your suggestions were very helpful.

I went through the troubleshooting and discovered that the problem was related to one of the extensions. The culprit was FBPhotoZoom 2.2. When this extension was disabled, the problem immediately went away.

Thanks again for your quick response.
