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

  • Switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • Do NOT click the "Refresh Firefox" button on the Safe Mode start window

Can you open the about:preferences page via the location/address bar?


The System Details List shows that you have multiple Flash plugins.

  1. Shockwave Flash 19.0 r0
  2. Shockwave Flash 21.0 r0
  3. Shockwave Flash 22.0 r0

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.
