[Semaphor]

I use FF and uBO (which has always worked better on FF than on the adtech browser), but I'd love uMatrix back. The interface of uBO is a typical mobile friendly simplification. As the article says, uBO can do everything if you are willing to write rules by hand. And missing is that the equivalent in uMatrix was a single click. Simply a huge step back in UX, and while I dropped uM eventually as the lack of maintenance resulted in incompatibilities, I'm now permitting far more connections than before as anything else would require too much work when I want to actually browse the web.
