I like how it removes all the video suggestions below any videos I just watched, so I don't have to scroll down ten meters to get to the comment section, which is the interesting bit. That is the reason I installed this extension. It is completely beyond me why youtube changed its layout in this user-unfriendly way and I hate them for it.
However, this add-on also removes all the video suggestions from the youtube starting page. But when I call up that page, the suggestions are actually what I want to see. I do that from time to time. There is a time and place for everything. This should be configurable.

I love it. I'm trying to spend less time watching YouTube, but there are a few channels I still think make content that is actually educational and good for me. This lets me remove most of the temptations to fall down the YouTube rabbit hole while still leaving the site perfectly functional.

Really great. It's amazing how fast YouTube loads without all those recommended videos.

It does not disable the playlists.
That feature is in the description and it is the only one that I wanted.
I don't know about the rest.
Therefore I give three stars instead of one.

Excellent.

Excellent! Finally someone got it right. Simple and effective. Feature request: Allow list of whitelisted words/phrases for channel name or video title for recommendations

So simple and effective. It'd be the ultimate if there were granular checkboxes to remove specific sections from the left bar as opposed to a mostly all-or-nothing approach, but the extension is nearly flawless in performance. Thanks!

Finally, I can now totally remove the comment section from all YouTube videos on Firefox for Android! Thanks for such an awesome extension!
