So far I am completely satisfied. Some videos cannot be downloaded, or perhaps converted, but the ratio of those that can and those that can't is very positive.

I have been using this extension for years and it works! It downloads from nearly website except Youtube but Youtube is hard to download from on purpose as they want you to pay to do that. I've used it a lot for porn and when videos appear on other non-youtube websites. I have been using Mozilla firefox for years too but this is the first time I bothered to make an account just to review this app and give it the praise it deserves.

Thousands of downloads (about 10TB). Found nothing better.

Normally I would use Ant Downloader, but you can't get all the components for Ant in Linux.

Video DownloadHelper does just as good a job. It downloads video, and audio-only podcast streams without any trouble.

This add-on works pretty well. I use a different software mainly to download videos from internet, but when it doesn't work, somehow this add-on works. It's nice to have different options, I guess.

A really good addon. Very helpful!

Used for a Vimeo "private" video. A couple of seconds after the loading of the page, the two videos are downloadable ! I am sad that it's not a free software…

straightforward and reliable.

very easy to use and straightforward

Quite simply the easiest way to download content.

Very good and easy to use, well done.
