Green screen on video, disabling hardware acceleration did not help

Hi, since a couple of days ago, I've had green screens appear on all videos that I attempt to play in Firefox. The audio still works fine, but there is no video. I have not installed or updated any add-ons recently. I do not have any problem viewing videos in other browsers (Chrome, Safari...) on the same machine.

Steps already taken: 1) Disabled hardware acceleration in Firefox preferences and restarted - no change 2) Set "webgl.disabled" to "true" in about:config and restarted - no change 3) Emptied cache and deleted cookie and restarted - no change

Any ideas appreciated, and happy to provide further details / logs if helpful

Wonder whether it's related to https://bugzilla.mozilla.org/show_bug.cgi?id=1546836 but I'm clearly out of my technical depth here..

You posted this while I was typing my suggestion to try to toggle that preference on the "about:conffig' page - had a look at that bug report and you're right.

Thank you for pointing that out  !

Hello mbimmler,

Would you please try this on the "about:config" page :

Type in the search bar :

media.wmf.dxva.

Search for the preference :

media.wmf.dxva.d3d11.enabled and set its value to false

Then close and restart Firefox.

Does that help  ?

Thanks McCoy, but I don't appear to have the "media.wmf.dxva.d3d11.enabled" in my about:config - in fact, I don't have anything with "media.wmf" at all.

When filtering for "media.w", I only get preferences beginning with "media.webrtc", "media.wave", "media.webaudio", "media.webm", "media.webspeech" or "media.webvtt"

Best, Michael

Thanks for confirming! Looks like they were able to fix it quite easily and in the time for 67b15 on Monday (?), so that should work again soon then :)

Note that Windows Media Foundation (wmf) is only for Windows OS and not for Mac (the OP is on Mac) and Linux.
