Great extension. Not all sites supported, but still good.

Thank you! Works great on the mobile version of firefox too! Just build your firefox collection, add it to mobile FF or fork, use it!
Forgot to add: the extension works on an open video tab, to download, play it first, then click on the extension icon and the download will start immediately.

It downloads videos very fast & it works well.
It doesn't work on every website.. but then I never expected it to be able to do so, especially on Websites like youtube that need to mix the video & audio streams back together again.

If you could update it to enable it to be able to capture the real name of the video that I am downloading (instead of the name of the video that is on the server) then that would be a great improvement, as it is fiddly & time consuming to have to rename every single video that I download.

Thanks.. great job as most of the other video downloaders that I use recently stopped working.
