I've using this extension for not so long but I'ts by far better than any other

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...

What good is an extension that doesn't do what it's supposed to do? What good is a download that is 0.0MB?

Has not worked in years. Why is it still listed in Mozilla addons?

DATAMINING AND THROTTLING. The extension worked at first, but they have a customized option in the extension's management section that gives the app full unilateral excess to your total web history, typing and any credit cards you submit while this extension is installed. An App that only works on Youtube should not have access to what Credit Cards or purchases I've made on Amazon. This is set to "default" upon install, and the Extension does not notify you of access to ALL websites. Already reported to Firefox for violations. Also throttles what quality you can download (falsely claims as errors when trying to download above 480p, but only AFTER you deny it's spammy (on screen) requests to give them money and "upgrade" the extension. So yeah, overall it data-mines you without your knowledge and the extension deliberately throttles your download ability after rejecting to upgrade. The "don't show notifications" option also does not work, because again, this Firefox extension is designed to delete your preferences only after 7 days so it can continue to send you spammy requests to "upgrade".

Appreciate much. Keep up the good work - I like your program; the best compared to the other online YT downloaders.  I have been a subscriber of yours for many years.

great!

Doesn't work with "You"

Funciona!

とっても使いやすいです
最高！！

소스 구하는 용도로 쓰려고 했는데
프레임, 비트레이트, 샘플레이트 다 작살내놔서 사용못함.

Fantastic! Absolutely the best. I've worked with a lot of tools, but in all my life I've never seen anything so beautifully simple. Recommended any day of the week, and the best out there. Any resolution, and it Just Works!
