It used to be possible right ? doesnt have to be a strictly youtube focused site either, being able to grab url from other sites are always a plus, only suggest apps that are on fdroid (main repo) .
Also for those who dk and might find useful you can use webtor to get a network stream url from magnet links, tho i wont suggest it as the lag and experience is abysmal and misses important functions like seeding .


Creating an addon collection as per this guide allows me to install computer addons to my Android phone:

The addon I use to grab streams didn’t want to work on youtube though, but it worked to grab video streams from other sites.

Ah well youtube is a must, thanks tho
Yeah, the main tip was that you can use whatever you use to grab streams from youtube on firefox on your computer and add that addon to a collection to get it on your phone.
I didnt read the article cause i aldready had a way to add computer only addons to ff android which is visit addons site in desktop mode and click on see desktop addons suggestion and get desktop addons from there .
Ah, I take it this is the tactic you use?
yes, the first sentence, i didnt have any problem so idk abt the rest, but i only downloaded one extension that one time then removed it half an hour later, i try to keep my extensions to a minimum, i have three now and two are disabled ofcourse ubo being the one always active
