Hello there. I've had this problem on 98, 99 and now 99.0.1 Whenever I am on youtube and click on a video, the video will play just fine. However, if I open a video in a new tab or I open a video from something like reddit or discord into a new tab, I get "a playback error occurred. Please try again later. I can recreate the problem very easily. For example, I just went to the homepage and clicked on a random video. It played just fine, but if I open a video from the suggested videos into a new tab, I get the error. If I click on the same video in the original tab, it plays just fine. Only if I open it in a new tab does it get angry. Now the interesting thing is, this happens randomly. it does not happen with all videos. If I didn't already watch a video on youtube and open a video from discord or reddit etc, the video is hit or miss whether it will work or not. Restarting Firefox doesn't help as I can recreate the problem and the problem also occurs in Firefox Safe mode. I don't remember having this problem before version 98. Thank you.
