Firefox Freezing on Youtube

There was nothing wrong everything was running perfect and smooth but then out of nowhere my youtube froze and I couldn't press anything on youtube tab, I could still close it or press the buttons on the sides/corners but on the youtube, it also doesn't refresh, this only happens on youtube and only on firefox when on other browsers, yes I unchecked hardware acceleration, I restarted my firefox many times, I cleared the cache, today I turned my adblockers too, i thought it turned into how it was before but then it froze again and now I couldn't even see youtube it was just black screen on that tab, like what do I do here, do I switch browsers? It eventually starts playing again after I wait for some minutes but I don't want that, I want it to work like how it did before this happened. Why did it even happen?!
