This extension is really great. It is frequently updated to keep up with YouTube's frequent code changes. Be patient.

Best addon ever for real! Old school heroes here!!

Works like Magic.

Super Great app

Great app

This allows me and my guest (grand kids, friends, and neighbors) to watch at my cabin or when i am not on Wi-Fi. I believe its the best and will continue to support this amazing project.

Excellent performance and quality, kicking the man in the nuts every time!

I had this downloader for a while now and it works like a charm, when you tube changes its code this guys work hard to learn the new code and fix the problem, it is the best downloader for firefox, I could not do without it

Always impressed withe this dev, always on top of the youtube code changes, simple and functional system, I recommend it highly!
Thanks! Been using his extension for three years never a problem! :)

I've rarely had any problems with this downloader. I'm wise to how the YouTube downloader game works, if the add-on doesn't work then Youtube changed their coding thus breaking the add-on so the developer has to sift though YouTube's code to rewrite their add-on's code to make it work again.

TL;DR If the add-on don't work, it's stupid YouTube's fault. Hang tight, Dishita's got you!
