I loved this, used it for years pretty much flawlessly but it no longer works on FF 57.0. The "interface" is horrible and it won't download anything anyway so I guess I'll have to try something else. Very sad.

due to new update (7.00) and firefox (v.57), this cannot be used???

A versão nova ficou péssima. Baixa em formatos criptografados o media play não ler

Great app if 60% of all videos did not require a paid companion app to go along with it.

How to define the name of the downloaded videos in firefox 57???? Is it still working????

since updated to firefox quantum i cant convert videos to mp3.
