What's your computer system and Firefox version?

See if this helps;

Type in the address bar about:config (press Enter) (promise to be careful if asked) Type in the search bar and look for the preference : media.wmf.dxva.d3d11.enabled And set its value to false. After, restart Firefox.

If this does not help, change this back.


Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
