There are so many extension that are hacks..this one works...it does take you to another page..but immediately does conversion in the page without other BS redirects. Once done..you can download it off the page.

it works! thanks!

Version 3.0.0 does NOT work anymore since last update (of Mar 16, 2021). Sometimes things like that happened so you just have to download the previous version BUT the developer STUPIDLY REMOVED all previous ones in version history. It's why I'm giving 1 STAR ONLY.

***UPDATE*** Guys, instead use the extension called: "YouTube Video and Audio Downloader (WebEx) by feller". It works like a charm AND it's recommended by FireFox

yes yes

So far, quick easy downloading.

As of 2020-10-28, this is the only extension that works.

JUST what i needed

完全没用，还各种按钮莫名其妙的广告什么的

Takes me to the download page which immediately goes to a blank page

Lame. All it does it paste the URL for you in a 3rd party downloader. Even then it doesn't work, the page flashes then disappears.

funktioniert nicht

It used to work fine. Then, suddenly 3 days ago, Zip, Nada, Nothing. The page just disappeared before you could hit Download. Removed it from Firefox Add-ons. Today I added it to the Add-ons again. I tried one single download to check if it works. It did. Great. Let's see how long though. You Tube belongs to Google and Google doesn't give Shit for free.
