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.
