Hi there, since the beginning of June (probably the update with the PiP notification) I noticed that a lot of specific Youtube-videos are endlessly loading (the spinning circle animation) and not showing any controls (play/pause, next video, etc.). It's not like I could try multiple times and sometimes videos load and sometimes they don't, it seems to be specific videos, but I can't figure out what differs them from others. Examples that work: https://www.youtube.com/watch?v=Yqy7_zUKyNQ https://www.youtube.com/watch?v=ftuctYN60j0 Examples that do not load: https://www.youtube.com/watch?v=FF3Dr3_h0Hw https://www.youtube.com/watch?v=LAN1LXO1eG8 Generally I could say that about 60% of the videos aren't loading. I tried them in another Browser and also inside of other Software (Discord, Mattermost) where everything seems to work just fine, it's just my Firefox having issues and I really don't want to switch to another browser. I really hope somebody can help me, I tried finding a solution, but all the other issues seem to differ from mine or are Mobile-issues.
