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

Best extension for all platforms for this functionality! Thank you!

Very useful, and it only accesses what we browse on youtube :)
