a free plugin that worth thousand dollars indeed,
can download almost all kind of stream video online and convert to formats you like.

I had to give 5 stars instead of 1 because the lowers rating doesn't show up. It used to be cool and reliable but now, THE APP COMPANION IS ADDING A REALLY BIG QR CODE IN THE CORNER OF EACH VIDEO YOU DOWNLOAD to it until you paid a license. There are third party apps that's works better out there.

very very good

One of the most usefull add-on. It's been years that I'm using it and always going better. Will be great if will be created a version of download helper for Firefox for Android, considering how much smart phones are used now.
