I've been using this add on without a glitch for a while now. Developer is very good at updating quickly when YouTube or FireFox upgrades break something.

Obviously, you need at least 3 different video downloaders in order to keep up with Youtube's constant changes, and this is one of my choices. It works as well as my other selections.

POR FIN UNA EXTENSIÓN QUE BAJA EN 1080 !!!! Gracias !!!!

A+ for user-friendly, A+ for functional, A+ for getting the job done with minimum fuss or hassle!!! Thank you Dishita!!!

wow WHAT A SUPERB UTILITY SOFTWARE EASY AND TRANSPARENT TO USE wow!!

Easy, fast video downloader on youtube. The Best I found and the fastest update and fixes.

Works as expected, thanks!

Just works well from the word go ... and now even better!

Works well, but if you want the upgraded PRO version that allows you to download high res 1080 videos, be careful how you go about it - I haven't been able to get PRO to work.

Doesn't allow 1080p unless you buy it

This is one of the best and favorite addons ever

It just works. most others get confusing to use, this one very simple and is updated...very nice.

With this add-on, I can download youtube video and play the video without internet. Thank you very much. Recommended add-on

Useless plugin unless you buy Pro! NOT recommended.

I really like this video downloader. Due to the lousy internet bandwidth I have, I'm unable to view videos, so I must download them first - unless I want to view a 5 minute video start and stop repeatedly for 20 minutes. This app fits the bill by enabling me to download them to view later on - then I toss those I don't wish to keep.

By far the best YouTube Download add-on I evaluated. I recommend this to all of my loved ones. Please support this author. A donation is a small price to pay considering how much of our time is spared and so much of their time is spent. This author has consistently kept up to YouTube changes for years, each time sparing hours of my life from searching and re-evaluating because other add-on's are time-consuming thinking they will work and do not, or are just not as nicely designed. To the author: PLEASE do not get discouraged and keep up the great work. I don't write reviews but I was motivated for this one.

A useful app for anybody who wishes to record info. for later use

Works well in youtube. Well worth supporting.
