Well developed and constantly updated. Very good extension for getting videos downloaded to external devices.

操作が簡単で手軽にダウンロードできます。
簡単が一番！

Having tried both paid and free video down-loaders, only to be disappointed and frustrated time after time, I have found VDH to be a really unexpectedly pleasant surprise. There are occasional glitches, but closing and re-opening FF generally sorts those out. Highly recommended.

Very powerful app

Awesome app! Keep up the great work!

Bien utile pour sauvegarder des vieux documentaires introuvables autrement que sur youtube!

とても役立ちます。

It works beautifully.
May i suggest an option for choosing default folder to save files? It defaults to system disk, and alternative to save as, is more clicks.

Pratico e veloce. Facile da usare
