If i could, i would give 8 out of five stars!
Very reliable app, only one which does eleminate adds for certain.
Lots of additional features!!

Great plugin to choose lower video quality for videos when having a slow internet connection or slow computer.

The only features I'm missing is to see the publish date of a video and second choice of video resolution. 480p is missing some time today and want 360p as second option.

1080p60 and 720p60 is some times an option. Is 30fps option of these videos missing or bug in this plugin?

great but when you are using it or maybe its just a custom deepdark theme problem the profile section in the library section of youtube gets cut off not by the screen its just cut off for some reason

good firefox Add-ons

I don't know why I have to use an extension just to make Youtube not forget sometimes I don't wanna watch things on 480p on an 1gb fiber connection. But i do.

This is the best Youtube extension since YePpHa's YoutubeCenter (if you know, you know). This does absolutely everything that I would expect a full featured YT extension should do, plus more, with plenty of customization options to suit 90% of people's needs - and for that last 10%, there is a custom script section for you to apply your own JS code. Highly recommended extension for YT power users and customization geeks.

eles bem podiam, fazer-isso para melhorar visual fifox

edit, missed the latest update, works as before, thx (never mind)

I really enjoy this extensions and all the ways it improves the vanilla experience of youtube! I do have a request/idea, however - I use another extension for management of text size and page zoom (I have middle-aged eyes), but it doesn't handle text zoom on youtube very well at all. None of the settings in the extension see, to be able to touch the size of comment text, however - when I select the option to enlarge text, it enlarges the titles of related videos only. And the whole reason I downloaded this extension was because if you use page zoom alone to try to enlarge text on youtube it makes the video previews enormous. I hope you see how helpful it would be to make this an option in the extension. Thanks!

this extension is 2good2Btrue

@Наско Ok sorry I was really mad. Thank you to make things clear. And the issue is fixed now. Thank you Dear Maxime...
