Despite what Dishita has said there is in fact a limit on how many videos you can download. For me it can be only 1 or 2 maybe 3, and on some days it won't download anything - which is to say it doesn't work...
When it doesn't work I get the 0 of 3 tries indication and the video doesn't download...
Seems to work somedays and doesn't work on others...
I agree with another review when it comes to being data mined. What business is it of this extension to know what (if any) credit card(s) information I have stored, or what I purchase from Amazon or other online retailers???
That isn't necessary for the purpose this downloader is supposed to serve which is to download YouTube videos...
As for the paid version, friends in the US tell me it's not reliable or simply doesn't work...
Likewise friends here in the Philippines say the same thing...
In all fairness it does work but is unreliable as a means to download more 1 or 2 videos if you're lucky...
