uMatrix has been archived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 <i>type</i> of request (i.e. cookie, image, XHR, etc).<p>Now, obviously you could always write an ABP compatible filter that could block any combination of these two, but that&#x27;s <i>hard</i>. What uMatrix did is present the underlying complexity in a way that&#x27;s easy to intuit for a power user, giving you point-and-click request filtering power over both domains simultaneously.<p>For that reason, I&#x27;m skeptical that uMatrix can be replaced with a traditional blocker, not even one with an advanced mode like uBo, because it simply doesn&#x27;t allow the specificity that a two-dimensional model like uMatrix did. That makes uMatrix&#x27;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.
