It has been updated, after a long period with no updates; it's now finally at the same version as the Google Chrome version.
It provides a lot of great features, which make interacting with Youtube a lot less addicting, frustrating and annoying. Besides allowing you to set limits on Youtube watch it includes toggles for hiding or changing most of the parts of Youtube — which are the parts I find the most useful. It seems to be working without issues, which is great to see.
It's great, I love it, and I'm so glad it's back.

Just because of the "Remove shorts" feature is worth 5 stars

Couldn't use music.youtube while block was active on youtube, unchecking the (Access your data for sites in the *://youtube.com domain) did the trick. Please add a feature or remove the permission

now i can hide those ****ing shorts! thank you, dear developer, thank you so much!

Fantastic extension. I really love it and it's my favorite extension, I just wish it was updated because it's no longer fully working

EDIT:
firefox version was outdated

This extension seems to create a memory leak in Firefox, and unfortunately slows down YT a lot in its process. Too bad, seemed really good on paper.

Thank you for addon works fine...

This thing is great

I havent used much and you seems so eager to improve your extension so i will write a bit..On firefox on android, column number does not work, which is what i expected because all other extension with this feature does not work too. also utube always suggest the same video over and over again ifu can stop that

A great extension with many useful features, but the slowdown is significant and very noticeable and needs to be tended to.

I really like it, but, unfortunately, it does slow down YouTube. Still usable tho

Nice bro thx

Just fucking great
