I used this and the videodownloader with some sucess for about a month but now neither work .Says it has downloaded vid but download has zero bytes and is moribund

뭐가 문젠지 모르겠는데 영상 다운 버튼 하나 눌렀는데 같은 영상을 수백개씩 다운로드 하고 있음. 브라우저 렉 걸리는 건 덤.

By default, it places an annoying button under the video window which displaces other YouTube options and there is no way to disable it.

Downloaded and tried it today (April 20, 2026), but it is not working. Zero bytes downloaded whichever type (480p, 720p, etc.) I chose.

Downloads one video successfully per 50-75 attempts. Most of the time it just "downloads" a video with zero megabytes.

This extension doesn't work as advertised. It simply does nothing. Not even the green download button that should appear on the youtube layout. Just the green icon on the browser toolbar with a message "generating link", nothing else.

Was a really good plug in and i used it a lot.
I payed for the premium version with pleasure.
But then, after 2 years, the premium version isnt working anymore for me.
So I ask the creator why and he told me that i need to pay again.
Like i already bought the premium version but then i need to buy it a second time ?
Im now using Notube wich is really nice too if you want.

Still does not work after update for 24.2 :(

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".

Doesn't work with "You"
