It just works.

Excellent add on

Been using for a few years. Works like a charm. Good and prompt support. Just be patient if it doesn't work due to YT changing something. It may take a few days to resolve. And buy coffee for the poor guy.

This add-on has been tremendously useful, particularly when working with students who needed to work asynchronously for these last two years. Thank you.

this add is very good,Simple and easy to use

The most reliable "Youtube Video Downloader" till date.

Recomendo fortemente. Esse é, sem dúvidas, o melhor, mais fácil e mais objetivo plug-in para baixar vídeos no mozilla firefox.

Have been using this downloader with excellent results for several years.

BEST YouTube Downloader embedded within the app itself and so easy to use! Well done!

Very useful and reliable, does what promised. First of all proceeds the 3GP 144p extension not available by most of
other developers.
I enjoy this extension very much, thanks.

I love this add on! It works Great! I use it all the time!!!

A really useful add-on for downloading YouTube videos.
