Was a great help for me as well for video and audio. It is especially good on Linux, because there it could be used without costs.

Great tool. Works excellent with youtv

The best video downloader for firefox. A must have essential addon for your firefox browser that cannot be beaten.

真的非常好用我想捐款来着可是我看不懂是哪种支付方式，我只会用Ali-pay

Sin ninguna duda.... la mejor extension para salvar videos en Firefox.

best downloader out there

molto valido

good S

Helpful add-on. It can download most of the videos.

Perfect! Very nice download media and easy use.

This is a fantastic add on. It is very helpful to save video and audio files for later viewing. You can change your settings to customise the formats you want it saved in and where. Very helpful. Been using this for a few years now. Would not be without it. Thanks guys

Elégedett vagyok, lehetne gyorsabb is !

Requires the installation of thrid party software which doesn't seem to have a proper uninstaller.
Also requires a (hidden) fee to have a proper usable video file.
