Garbage. Annoying location for download buttons (half covers the Youtube channels user icon) and sends you to an external site to download the video. When downloading a video it downloads as a zip and in WEBM format. I tried to get a 480p video and I get one 480p with no sound and a 360p video with sound and no video.
WHY?!

not work

"Sorry we cannot download your video - you can download it with this great tool" in 1080p video.
Typical advertising addon to promote a third-party program. There are hundreds of them here. Don't waste your time.

it's good and for the pub i use malwarebytes,decentraleyes,adGuard adblocker and privacy badger ,it's cool,but don't use this add-on by Ugafan ,name: Loader.to all-in-1 helper / youtube downloader par Ugafan,they never work very well,use this one,name: Savefrom YouTube Downloader par Ugafan,it's very good ,and sometime i copy the url from chrome,or from duck duck go search engine,and never connect to youtube by google and block that shit:
phortaub.com

www.googletagmanager.com by malwarebytes add-on;,and if the add-on from firefox it's too slow,copy and paste url by chrome, !!! enjoy !!!

scam ads on the website the addon takes you to, which do not go away, nor have an "X" to rid the scam ads. Worked decent before, but now ruined by the adds

It works with resolutions of 1080p and up.

It is *impossible* to download a video with this extension. They just want to load malware on your browser.

good addon, i recommend, is fast, malwarefree and free, no errors nor faulty downloads, so far so good

As of 16 December 2021 something has gone wrong with this downloader. It now takes me to an ERROR 1020 page. Is this something that can be amened from your end? I'm now having to try and use an alternative.

Doesn't actually download anything. Just provides a link to a page that takes forever acting like it's downloading something and then redirects to a spammy malware site.

Useless extension that redirects you to some site instead of directly downloading the video from YT.

Funciona Perfectamente. descarga en full HD y con sonido

Actually worth getting. I'm sure it'll get better as time goes on too.
