I am trying to delete the add on extensions and when I click themes and extensions, manage your add on does not pop up. It is causing problem with trying to download videos with dwhelper because the add on extensions pop up not the video download. Please help. Thanks

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
