It looks like another addon was phoning home to a blocked resource. I should've tried more combinations first. The best thing I can think of is that it would be cool if uBlock reported when a call from another extension has been blocked.

That is the purpose of the built-in logger[1]. By default uBO is not setup to block other extensions' network requests, or those made by the browser itself, one has to configure it explicitly for this to happen[2].

Hm OK, must be something else then. Either way, uMatrix blows Ghostery away so this has been fortuitous.

I'm using it now at the recommendation of people here, and you're too right. It's a bit like going from a pogo stick to a McLaren.
