Can't get pop-up blocking to stick. I have the check the box again every time I open Firefox. Any suggestions?

I am unable to eliminate pop-ups. Firefox is opening every time with pop-up blocking disabled. I manually check the box and am good for that session, but blocking is disabled again when I open a new session. This is a new problem, as I have used Firefox for many years without pop-ups. It may be coincident with upgrading to Firefox 4. How can I get pop-up blocking to stick?!

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
