looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don’t run a complaint browser ( cough…firefox )
here is an article in hacker news since i’m sure they can explain this to you better than i.
and also some github docs
I found that quite easy, for once: I have a bare NC instance and I installed 2 add-ons (the integration bits and the CODE server that IIRC drops an appimage of the actual collabora server). Unless you have hundreds of users, that’s about as much admin as you need :)
I’ll give it another try then, thanks !
