Yeah hence “supposed to be”
I’m only semi-tech-literate, what is this manifest 3 thing and why does it kill Ublock? And if chromium is open, shouldn’t forks be able to modify whatever manifest 3 is to restore the abilities Ublock needs?
I don't know all the details but I believe uBlock Origin relies on very long lists of servers that serve ads and declines to download from them, and manifest v3 limits the length of those lists so that they have to pick and choose which ones. Hence the uBlock origin lite, the lists are shorter.
