Hello dagwood52,

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:

  1. Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux).
  2. Select the General panel.
  3. Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.

  4. Uncheck Use hardware acceleration when available.
  5. Close Firefox completely and then restart Firefox to see if the problem persists.

Did this fix your problems? Please report back to us!

If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:


In case the above doesn't do the trick :

Type in the address bar about:config and 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

Then close and restart Firefox.

Note that the green window is a placeholder for the actual media player, so if you see this green window then this means that Firefox isn't able to create the player.

Hopefully disabling hardware acceleration like suggested above will work.

You can check the Web Console to see if there are messages about your issue.

I disabled hardware acceleration and it still came up with a green screen.

How about my second suggestion to change the value of media.wmf.dxva.d3d11.enabled to false on the about:config page  ?
