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.)
