Top 10 Firefox Add-on.

Instantly removing due to inclusion of pop up ads. How in the hell are you going to have an app that removes YT ads then hits you with its own popup ads?

In version 2.0.17 the option " Use the available space based on the viewport dimensions to expand the video player " doesn't resize the video correctly, it's taller than the viewport and the control bar is displayed off screen.
Now has ads.

I'm missing 1 feature and that is bookmarking a YouTube video where you can timestamp the video so whenever you left, you can watch it again on that timestamp.

i like it!
its great!
i use it everyday.
one suggestion, i would like to control the "shortcut key" to reverse or forward the video as i would with keyboard from my mouse. thanks a lot and good work.

Now has ads

After a recent update 2021-09 it has disabled using my mouse wheel to control video volume of YouTube videos—unless I reload the web page—a nuisance. Videos opened in background no longer allow scroll wheel volume control. When it is working after a reload, if I click a link to another video the volume control is OK. It is not working when I load a new video in the background. So sad. How can I restore the older version?

Complemento indispensable para aprovechar youtube al máximo

Been an absolute must have in my browser since I discovered it, however like others have said, the scroll wheel volume control has been broken, working on/off since last update.
And causes videos to load slower, sometimes even buffering for 10 seconds before the video finally plays, sometimes it will load indefinitely.
Seems the addon has a problem hooking to the page, sometimes it will not have any function at all.

A true must-have add-on for Firefox, it makes YouTube bearable again. I really appreciate the ability to allow ads for channels I subscribe to.

Great extention. The JS injection feature is great. A CSS injection feature would be nice.
