youtube isnt working correctly and i cant get any helpful info

on and off issue for a few months now. i dont know if its a firefox issue, a youtube issue, or something else about my laptop. everything says i have the latest update, maybe part of an update broke youtube, i dont know for sure but at this point i have to assume its firefox because it works fine in another browser and mobile app, but i highly prefer to use firefox sometimes a video will play normally until i "interact" with it: if i have to pause, it wont unpause if i fast forward or rewind, audio will do so but the video will not. or vice versa if i click a different video, whether the current one is done or not, the new one might load 70-75% but not complete and just stay on the current video after any of these happen, the page is basically unresponsive; i can open a new tab but youtube will not open in that tab, but anything else works completely fine. if i close the tab or browser, there is a delay before it actually closes and sometimes the audio is still playing after the browser closes, in which case i can only restart my laptop entirely. ive tried to reprt this to youtube but i dont trust it actually got to human support. i also tried the "report a broken site" in firefox the other day.
