Youtube Constantly Buffering after Pausing and Resuming
I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

Ok well I restarted my computer a couple hours ago and haven't run into the bug since. I'll post here if it happens again

Does it still happen if the Unreal Engine window is not fully covering the Firefox window?
Things to try/experiment:
- Go to about:config and change media.suspend-bkgnd-video.enabled to false.
- Set the environment variable MOZ_WINDOW_OCCLUSION=0.

Thank you so much, I modifed the two values you suggested and my issue hasn't reoccured!
The problem has resurfaced, and now I don't even have to switch to another app. If I simply pause the video for more than a minute or two and then try to resume, the video buffers but the audio resumes, and I am forced to scrub back and forth through the video to fix it
Now if I pause and resume the video in the span of <5 seconds the issue occurs, and the audio also appears to be lagging but that could be due to my bluetooth headphones
Edit: This seems to happen randomly now, and the timing of the pausing and resuming doesn't appear to affect it
Edit 2: Pausing, switching to another tab, switching back, and trying to resume it is the most constant way to trigger this bug for me

Something interesting I just discovered, if I disconnect my Airpods then the issue stops happening

Now, around 50% of the time I click on a video on Youtube, I don't have to pause, resume, or even click anything; this bug happens right when the video starts.
Still limited to your Airpods? You could try testing some older versions of Firefox with mozregression to see if it ever worked before and find when it broke.

I used that tool and found the issue went all the way back to version 84.0a1, and I tried two versions before that (76.0a1 and 73.0a1) and neither of them would play sound from a Youtube video, not even when I disconnected my Airpods. I'm charging a different pair of Bluetooth headphones and will let you know if the issue happens with them.
This issue doesn't happen with the other pair of Bluetooth headphones, only with my Airpods
Edit: They are AirPods Pro (2nd generation)

Here's a profile I took, where I resumed a video while having my Airpods connected, the video buffered, I paused and resumed it, and it continued playing https://share.firefox.dev/3DwIXyA
