As soon as I log onto Firefox a box title JavaScript Application keeps popping up and it says unistall set. When I close it it pops up multiple times back to back. Stopping me from browsing.

This issue can be caused by an extension that isn't working properly.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).


In Firefox 4 you can use one of these to start in Safe mode:

  • Help > Restart with Add-ons Disabled
  • Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)
