hasta el momento es la mejor extension que he probado...

One of, if not the best Mozilla add-ons in history. I have using for 6+ years. Virtually flawless performance & pertinent, infrequent updates. Be sure to donate - even modestly - for this valuable extension!

Excellent add on and amazing results!!!!

cooles werkzeug

Great addon! I used the free version, really enjoyed and was glad to see that it grants Linux users a free license. Regardless, still paid for a license to contribute to the project. Really good!

New version adds giant QR code watermark to downloaded videos, removable by paying for the license.

Uma das extensões mais úteis nos navegadores.

Does not offer MP3

Indiscutivelmente o melhor. E a nova versão melhorou o que era bom.
