black screen at Facebook.png
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0
Steps to reproduce:
Any video on Facebook, when I play them and then click enlarge.
Actual results:
I can play them in feed, but when I click enlarge, it always shows black video feed when enlarged while still playing the audio.
It also happens sometimes with youtube, but on youtube when I hit refresh, it at least shows picture again after the refresh.
Expected results:
to show a video feed.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
I'm having trouble reproducing this. Does this happen with the following video? https://www.facebook.com/agreatbigworld.music/videos/294171351655262/

I can't see the video, it says "This content isn't available at the moment" but it happens with every Facebook video and has done so for months.

Just an update, I went into agreatbigworld's videos and played some of them. They worked fine.
It seems it's not every video, but instead it's every video in any feed such as my home feed. When I enlarge them they become black while playing audio.
They also sometimes turn black just when I scroll down the feed, which is fixed by me refreshing the page, like when youtube videos sometimes turn black when starting playback which is also fixed by hitting f5.
Thanks for the extra information. I have an idea on what I think is going on, but could use some more info to be sure. Could you navigate to about:support and use one of the buttons there to copy that information and post it onto this bug?
Thanks. Could you test if the issue takes place with a new profile? You can go back to your existing profile after, I just want to see if the problem is related to profile configuration.

Thanks
It did the trick. Then tried starting in safe mode and also no problem there, so it seems it was one of my extension.
Weird thing is I turned them all off, and then turned them on one by one. The problem didn't reappear with them all turned on.
Oh well, at least it works now, hopefully it will last. :-)
Thanks for testing. That is weird, and makes it hard to nail down the exact cause. I wouldn't think it highly likely, but if you have addons that modify the same configuration, then the order they're enabled in can be important.
I'll resolve this for now, as it sounds like an addon issue. Please reopen and need info me if the issue reoccurs and we can debug further.
