You can check for problems caused by a recent Flash 11.3 update and possibly downgrade to Flash 11.2 or 10.3 or disable protected mode in Flash 11.3.


Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Thanks for your help. I uninstalled version 11.3 and downgraded to 11.2. This seems to have done the trick.
