I have Youtube signing out problems as well. I also couldn’t subscribe to channels ‘cos it says I’m signed out even when I’m not. I also use Firefox. I saw a suggested solution to this that worked for me (while we wait for a better, official solution by Kaspersky). Settings - Network - disable “Inject script into web traffic...” then restart computer then my Youtube worked as it should after that. Just read the warning that pops up when you disable, if you’re ok with that.
