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 think they’re referring to the storage service at sync.com, not Firefox Sync.
Correct
How do you like it? Would you prefer it over dropbox, or not really?
I prefer it to drop box, it’s a better service and I believe not owned by Google like drop box it
