Firefox for Enterprise Support Forum

Hello, ever since we moved endpoints from Firefox ESR 91.13 to 102.3, it has become impossible to play any media with Firefox.

No video will play in youtube, for instance (it just loads endlessly as if it would start, but it doesn't).

Can't use radio websites either. Anything with a "play" button (video or sound) does nothing.

This has been tested with a clean profile, a clean install, after allowing autoplay in the settings.

Is there any info on what exactly changed between ESR 91 and 102 that might explain this ? There has been no system change, If I reinstall 91 instead it works again as usual.

No issues anywhere else on the endpoints (Edge, Windows), this is on Windows 10 if it makes any difference.

Tanks for any help on this.

Good morning,

I'm reaching out to see if I can get some assistance with Firefox on of our network. I'm System Admin at Goodfellow AFB. I've tried searching this issues on the web and found similar issues but solutions that were recommend online have not worked for us. Yes I have uninstalled Firefox completely and installed it from scratch. I know it has something to do with autoconfig file but not sure what exactly I'm looking for. Thanks.
