Works great, but shows three videos on the end screen now even if endscreens are turned off.

This is amazing. Thank your so much. You are saving our kids.

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

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firefox version was outdated

Thank you for addon works fine...

This thing is great

Nice bro thx

Beautiful. It just works. Distractions eliminated. Humanity restored.

Lovely extension that helps you manage the appearance of youtube to your exact liking
