Excellent ! Merci pour votre extension !

Strong feeling it's a kind of scam. I want to download an old 5min video of 1965, really basic and no HQ encoding at all, but I can't do it, I must install televzr. Ok, try it in a sandbox, want to test it so I decline premium payment. When I want to download, I got a message "You've run out of free downloads today, upgrade to premium" while I did zero download.
So I don't know if it works or not, but it's pay first, then maybe, it could work... No, thanks, I'll pass, given the low quality of the video, I'll use other mechanisms.
