I was shocked that this actually worked !!
True it opens up a window to a website that does the work, but after trying countless broken addons that do nothing, or install bitcoin miners, then I really don't mind.
I just bookmarked the website and removed this addon.

This actually works, it takes forever for the website to rehost the video, but it works. Just be patient... and make sure your add blocker isn't shutting it down (that was the problem I was having at first).

Very very good! Help a lot!!

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 !!!

It works with resolutions of 1080p and up.

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