One of the must-have extensions. Already works in the new WebExtentions framework. It stays out of the way, but works as intended.

Well put together and full of useful features.

Indispensable !

AWESOME!

Love it, makes youyube so much more bearable

Thanks for all your hard work

Great add-on.. thank you.

Great plugin.

Works Like a Champ.

Great

The best addon for controlling all features youtube related. And the only one that actually works to block youtube ads if you want. So awesome!

Works great

Great addon with essential functions for my YouTube-itis :) . I've set speed to 1.2 (though it's rediculously easy to change on the fly) and resolution to 360, as I watch mostly talking heads. Saves time, bandwidth and less congestion-hiccups. Ad filter, but I've whitelisted ads for my fav channels I want to support. More bandwith savings with no preload, pause in background, it's just all there, with good pre-settings, just install and run with it. (Real geeks can have fun adding cusom scripts.)
