Consistently awful media playback

What happened?

I've experienced terrible media playback issues throughout my entire use of the browser (over a year now of updates).

YouTube videos have issues stopping on a random frame, and reloading doesn't help when this happens. The browser just finds a new spot to freezeframe on while the audio continues to play. I have never had this issue on any other browser.

YouTube videos will also hesitate to pause or let you interact at all with the video player to varying degrees, but the issue is consistent; if the browser is open for longer than a day or two, a delay begins in the video player regarding any sort of interaction. The delay starts off between 1-5 seconds but as the browser stays open longer it can get up to a horrendous 8-12 seconds. The remedy is to restart the browser entirely whenever it begins, which as explained earlier gives you about a day or two before it's back to the same issue. I have never had this issue on any other browser.

Pretty much any video file you can play through waterfox in a tab seemingly has about a 70% chance of just stopping playback completely around 5-ish% away from video completion, making reloads or tricks necessary to loop the video. I have never had this issue on any other browser.

These issues seem entirely unique to waterfox and as I said, they've been consistent throughout over a year of continually updating to the latest version. Will not be using this browser anymore in the future, but I seriously hope these issues get addressed for the sake of the people who will. Until then, I can't in good faith recommend the browser to anyone.

Reproducible?
