My most used Extension on Firefox, now working flawless!!! Thanky

Superb!

This add-on contains lots of bugs. First; it extends the lenght of player so if video is 16:9 it becomes much more long in player base and i have black bars on top and bottom of the video. My YT home page and YouTube users' profile pages also broken because of this add-on. They solved lots of bugs so i am just turning it off for now, i wish they can solve new issues without any more time.
Edit: "Limit Page Width" solved the bug which i mentioned (video width and home, profile pages). Thanks. But changing thumbnail quality breaks thumbnails to gray boxes.

This is really wonderful.

Good one

yes it is quite good

Amazing work that i will definitely try. I recommend all of you to use it.

It is just amazing

The best!!

Very nice extension

It is a good one. It made my other YouTube adjustment add-on redundant, while also bringing new functionality. My only complaint is that it turns the page to Dark Mode all the time, no matter what I do. It would be great if the develepers could fix that. // Thank you for the response. Unfortunately, the improvement comes with a setback. I can now switch the dark theme off, but instead the Home tab produces glitches. If I start from there, it never loads, and the line of tags on top is flickering. I have changed the settings to start from the Subscriptions, and going from there to the Home tab results in inconsistent behaviour. Unpredictibly, previews are loaded in two columns or four.
