STABLE version -- 4.3.9.248

It's still there. It's called Shields.

yes, it might possibly be for tracking only as it is not blocking ads.

try removing (uncheck) any subscriptions for external lists under "subscribe to filter lists". Exit and start it up, I found all my normally quiet sites have ads...like "shields" is not working although it says it is on. 

so, you must subscribe to external filters as there is no internal filtering (except possibly for tracking).

At least that was a version or 2 ago. I'm using 2.4.4.3 beta now (all after that have caused the browser to crash when I right-click close a tab.). That's what happens with me. Shields will have no counts or minimal...
