This is a very reliable add on but is not working with all sites. For now is my only down-loader for this browser. However sometimes I use another browsers or stand alone down-loader's but for this browser I think is the best by far.

Couldn't give a 4.5, which is probably the most accurate. Used it for YEARS and works probably 90% of the time! My "go-to" app. Biggest complaint is when there are several videos on one page, it's sometimes hard to get the exact one that you want. Usually trial and error, just keep downloading and playing until I get the correct one.

this is a good Video downloader, took a bit to learn how to use it, but once you figure it out, it's functional. plus it's free ^_^

very helpful app!thank you so much!

It's great easy and free.

Perfeito, funciona muito bem. Perfect, works fine.

Best! Never go away please! ♥

An excellent and very stable extension. Highly recommended for downloading videos!

Works on a whole bunch of sites. I've downloaded over 100 videos at this point and all play perfectly.

the app is really good, it helped me a lot

Great app works a treat

My fav downloader! I've been using it quite for a while now. Not intense use. It's not mig's fault, but having to install extra plugins/addons to be able to choose the best file formats is a real PITA. Anyways, I recommend it over others.

Extensión fácil de usar y muy configurable. De los addons de descarga de vídeo para Firefox más efectivos. No es compatible con absolutamente todos los servicios web de video pero si con la gran mayoría incluso Youtube a dia de hacer esta reseña.
Este trabajo merece ser apoyado por todos. Un saludo y espero que siga así mucho tiempo.
