The issue i have noticed is when watching any YouTube video and if i decide to skip to a different time in the video it will cause it to go to a white screen, loads for at least 1-10seconds and then starts the video playback ( it can take multiple skips to get this white loading screen to come up ). Some cases the video quality will drop to 720P when i have set it to 1080P. I have attached the screenshot what it looks like as well as the stats for nerds page showing network connectivity stats. -I thought it was my computer until i tested this with multiple computers as well as on different network connections ( speeds up to 100mbps and even higher download speeds ) -Firefox has been completely uninstalled and reinstalled -tested in troubleshooting mode + no add-ons installed -Same on Private Mode and Normal Mode -updated to version [https://www.mozilla.org/en-US/firefox/104.0.1/releasenotes/?utm_source=firefox-browser&utm_medium=firefox-desktop&utm_campaign=about-dialog 104.0.1] but i think this fix was for a different YouTube issue -I even downloaded an older version like version 80 or 90 if i remember and still had it happen -Tried using some YouTube extensions like YouTube enhancer but that seems to just allow you to force the video a specific resolution As mentioned above to try and reproduce this issue, open any YouTube Video and just start skipping the video to random timeframes and see if it gets the white loading screen. I understand that when skipping the video it will start to buffer and this normally takes couple of seconds and starts playing. But with this white loading screen it can take up to 10 seconds to load and then starts playing Same issue described on Reddit https://old.reddit.com/r/firefox/comments/vhbce5/firefox_is_lowering_youtube_video_quality_randomly/
