Pop-up window opens when firefox is open. Cannot close to use the browser. How can I get rid of this?

There is no text in the pop-up window, and when I click outside the window, there is a tone 'error' that plays. The only way I can close Firefox is to open the Task Manager and end task. I deleted Firefox on my computer and reinstalled, and it has not solved the problem. Included is a screenshot of what it looks like.

This can result from the AOL toolbar.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

  • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
  • Do NOT click on the reset button on the startup window Mode safe
