Good work

I always get 504 gateway timeout

It doesn't appear on pages. Like most other Firefox add-on's that used to work... it doesn't anymore.
Firefox is a shell of what it was, pretty disappointing.

I had the same problems others have reported especially the virus aspect of this program, it does not seem to be an application I am going to keep it's just to sketchy.

Perfect

Doesn't work in USA.

te pone dos botones en la parte superior del video, lo que hace que el video descienda y tape x lamitad eltítulo del video, lo cual, queda bastante mal, así q va 1 estrella y desinstalación.

Funciona bem! Mas tem que ficar esperto com os AddOns. Quando as conversões estão sendo feitas são abertas muitas outras páginas e algumas com downloads de softwares suspeitos e falas mensagens de atualização do navegador. Não aconselho para quem não tem experiência com as porcarias da internet.

Excellent

Best converter I used so far. Simple and flawless

Аналогично этому https://addons.mozilla.org/ru/firefox/addon/download-mp3-youtube/ банально переводить на сайт-конвертер + не работает на старом стиле YouTube.

This is the one I like most from what is available for the job. But my Avast finds it 'unreputable' and wants to remove it.

Love! Gives you lots of options for slow connections and worked instantly. Also keeps the original name of the film.

High quality (320kbps) downloads. I love it.
