Very useful and easy to use. The ability to add custom scripts is a great feature.

Essential !

The best youtube feature/qol extension i've ever tried (and i've tried just about every one)

great for big users of the site

great customizability

acually being updated alongside youtubes newest changes

This is a great add on. Love all the features, especially the ass blocking.

I think is simply it's the best, nothing to say more :-)

AWESOME I watch YouTube videos all the time and I HATE the advertising, especially the MORONS who put ads every 5-10 minutes! With this Add-on I can watch without ads. Now I never use any other browser than Firefox for YouTube video watching. :o)

Me permite personalizar youtube a mi gusto y usanza, es muy buena extensión.

Adds usability features to YouTube without getting in the way. Nice job.
