This is the one and only legit Ublock Origin. Yes, the link name might appear misleading, but a look at the author (gorhill) and the about (Ublock Origin) will remove any doubt about the authenticity.
It's the best ad-blocker available and has been for some time.
It is. No point in using any of the others in my opinion.
Considering that this is from Raymond Hill (gorhill), I'm 99% sure that this one is the good one.
Ublock Origin is the good one. Ublock is bad one.
Correct. Not sure why the OP is getting downvoted as that was a reasonable question. It would be easy to mix up which of "Ublock" and "Ublock Origin" should be used.
Sadly becoming something less than it was soon, due to the constraints of manifest v3.
Most of the shady ones aren't going to be open source, for one thing.
searching for github and gorhill will not lead you astray, at the moment, for an authentic ublock
