I honestly thought I was just having bad luck with Firefox. Whenever it occurs, I take the link and throw it into freetube.

Here’s the article. He showed in the video, https://www.ghacks.net/2023/11/20/youtube-video-loading-delayed-fix-inside/. I used the uBlock Origin Filter and it works.

The video is bunk, the original "analysis" was wrong, they didn't look up what the function actually does, the function is showing up in other browsers. It's pretty clear this is an A/B test rolling out that's fetching something behind the scenes that's broken for a bunch of people.

Jumped to a conclusion without even understanding the subject at hand.

Reddit is also slowing down Firefox. This shit needs to stop.

Youtube makes the video stutery too sometimes on my firefox

I think they are trying another random testing because this happens to me from time to time on brave browser too.
