Firefox 企業版 技術支援討論區

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.

Hello, I have a problem with setting up HTTPs only Mode in my Organization, I read a lot about that, but I dont see the "dom.security.https_only_mode" switch in GPO, we have the newest admx for Firefox. We need that to specific container, but still I dont know how to set it up, even via regedit, or preferences. Can someone describe me when can I set it up ? It could be using json file (which exactly file and how?), registry or just gpo. Regards, M.

Environment:

• Version: 102.3.0esr
• Build ID: 20220912135840
• OS: Windows_NT 10.0 19044

Issue: I had Firefox window 1 opened in virtual desktop 1, then I switched to virtual desktop 2 and open Firefox window 2 there. After using window 2 for some time, I switched back to virtual desktop 1 and found Firefox window 1 was gone. I checked `about:support` page but found no crash report there. I don't know what's going wrong.
