Hi, I have recently encountered an issue where the video players on certain websites will cause firefox to freeze - the loading animation on the tab plays, but no window of the browser can be interacted with (including very basic interactions such as how tabs normally become highlighted when you mouse over them). I have encountered the issue on disney+ and skillshare but not netflix or youtube, leading me to think that it might be to do with the DRM that those sites use? The issue does not occur in troubleshooting mode but does in private browsing. I have tried disabling all of my add-ons and clearing my cache (though the "clear recent history" menu), but neither has solved the problem. It is unclear to me what steps more I can take other than resetting my browser entirely, which I'm reluctant to do as an add-on that I use has a somewhat lengthy setup process which I would prefer not to have to repeat. Any help would be appreciated!!
