Simply: It works, it's easy to use, and it's very useful. Dishita is diligent in updating and getting past YouTube's tricks that could block it.

Excellent 1-click downloader, very easy to use.
Dishita, i really appreciate the work you have put into this programme.

I love this extension, works great for me and everything is fine. But is there a way to download a playlist, because I cannot download every single music video out of my 225 videos playlist individually. Please add this feature or tell me how to do it, other than that the extension is great. Thank you Dishita!!

does what it's supposed to do, and it's not too invasive on the youtube website. 5/5 stars

not a fan of the new interface... not sure if it is really downloading or not now. Been a long time since i last used it but this is just weird. IT IS WORKING for me without issue. Not sure what all the complaints are about below me..........

disabled my youtube music. finally figured out which exten it was and disabled all of the optional tracking on this, finally worked.

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".
