YouTube has become so bad that I had to resort to Tampermonkey scripts to become bearable.

First was the disgusting pink tones in the progress bar. Then the oversized thumbnails / less videos per page. Then the horrible over sized player controls. And now the oversized suggestions on the side bar.

Not to mention the obnoxious amount and duration of ads.

It's getting worse and worse.

These are all symptoms that something is very wrong.

you can do all this with one extension and no scripts: Enhancer for Youtube.

Also recommend DeArrow and SponsorBlock.

But also flip content creators a $5 every once in a while. That's more revenue than they'll ever get from you watchin their videos.
