uMatrix has been archived
IMO the genius of uMatrix was that Raymond realized that an in-browser requests firewall should have two dimensions, instead of one: (1) the (sub-)domains that the requests pointed at, and (2) the type of request (i.e. cookie, image, XHR, etc).Now, obviously you could always write an ABP compatible filter that could block any combination of these two, but that's hard. What uMatrix did is present the underlying complexity in a way that's easy to intuit for a power user, giving you point-and-click request filtering power over both domains simultaneously.For that reason, I'm skeptical that uMatrix can be replaced with a traditional blocker, not even one with an advanced mode like uBo, because it simply doesn't allow the specificity that a two-dimensional model like uMatrix did. That makes uMatrix's being archived incredibly tragic and a great loss for the web. I hope someone as trustworthy and competent as Raymond will pick it up in the future, and I thank him for all his work on it up to this point.
