Hi, i got a problem with Firefox 86.0 after last update. Firefox freezes when I switch video, skip ads or go to main page when any video plays on Youtube. But there's interesting thing: if i pause video first and then switch to another, all right. But if i don't pause, firefox freezes with 100% CPU load. I have never seen that problem before. I tried these steps, but it wasn't helpful: 1. Disable recommended perfomance settings and hardware acceleration. 2. Clear cookie, cache and startup cache. 3. Safe mode with disabled plugins. 4. Refresh Firefox. 5. Full uninstall Firefox and install again. I don't know what else i can try to solve this problem... Please, help!
