Please install the beta version 7.7.0a1
Previously with the stable version, Youtube and other sites changed something and this extension had become rendered purposeless.
And now it back to working again, not to its full glory, but working when required.

Great !!...

I can't thank the developers of Video DownloadHelper for creating one of Thee BEST Video Download Extensions ever created for Firefox! Simply Outstanding! I use it all the time. Great features, regularly updated and well supported. Thank you, again, to the developers! You are much appreciated.

best! simply that.

Es lo que necesitaba

Video indirme konusunda çok iyi

Este sa mi nic nepodarilo stiahnut ale ja sa to naucim.

Dear developers. this add-on is amazing. I love you guys.

MUITO BOM!

It's an important and easy to use extension to Firefox. Just start your video, wait some 20 to 50 seconds to allow synchronization to be initialized, then click the three balls logo of the extension, and click the row where the word "streaming" appears in the open curtain-menu. Video DownloadHelper will start the conversion to standard .mp4 file warning you of the running process with a "1" over the three-balls logo.
It also warns you when your conversion is accomplished, so you'll find your complete .mp4 file under 'yourcomputername'/dwhelper.
Really one of the best downloaders, with recently improved easier interface.
Best dpwnloader, now also easy to use/

this extension is a life-saver!! i downloaded literally hundreds of hours worth of lectures from a subscription-only website. i'll never have to pay for it again. and the video quality is great. cannot thank the developers enough.

Its great! I like it!

Able to download videos where other services failed.

muito boa
