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!!!

Very fine work done with this add on. Invaluable for users,

A really useful add-on for downloading YouTube videos.

Ничего не скачивается уже давно.

Simple and easy to use. It has been reliable for me for many years.

this extension kicks ass ive used it repeatedly over the years and yes sometimes youtube causes some difficulty it remains reliable and user deticated.
