I add this immediately to any new computer. It is probably the extension I use most.

Très bonne extension pour télécharger des vidéos, mais c'est un peu plus compliqué pour la conversion....

SEHR GUT

getting better all the time

Cet addin a tout : facilité d'utilisation, adapté dans de multiples situations.
Essayer c'est adopté !

Однажды я долго искал нужный мне контент, спросил друга где он находит качественный контент и посоветовал мне это расширение, сейчас я очень доволен что хочу выразить благодарность разработчикам, респект

very good application

Отличный плагин

One of the easiest to use and most effective video downloading add-ons and my favorite on Mozilla. They are constantly upgrading it as well.

Works very well, with flexible options. Displays file size, which can make it easier to pick out the right file on a busy web page. Better than others I've tried.

I am happy with this app. Has not disappointed me

Useful the Add-ons, work well as all the times

i use it regularly.
it easy to use.

I've recommended this add-on to many people. It doesn't download everything that I ask it to, but is perfect for youtube videos and many other sites as well.

I like it!

點選即可下載，很是方便、有效。非常謝謝！

This is an extremely great add on for Firefox. If I can afford, I will donate unreluctantly.

Downloads very fast

非常不错的软件。
