Firefox on Windows 10 seems to have problems where YouTube tabs, specifically, will go nonresponsive and not want to react to clicks for long periods, if I have opened one or more tabs with long videos. I've also found that when RAM gets low, I can close a tab which is playing audio and it will continue playing the audio for sometimes a good 20 or 30 seconds before the audio stops. I have never seen these issues on Linux. Has anyone else seen this?
