It's saved me! Rated 5 out of 5 stars

I couldn't download a video I really liked! Even DownloadHelper didn't help! Somehow it saw the video and it's quality, but it downloaded it with 0 Mb size. Probably the user, which uploaded that video had found the way to block users from illegally downloading it. I searched this whole site, tried practically every add-on, but nothing worked! I was becoming desperate. But then this add-on worked and I was really happy!!!)))

This review is for a previous version of the add-on (1.7.9.1-signed).
