Version 1.2 now has a counter of blocked requests.
I don't think I'm going to add regexp. But it is possible to combine this addon with another one that will block requests based on regexp filters for the few websites that still display ads after Javascript Firewall blocked unwanted scripts.
There isn't a proper way for addons to cancel the creation of cookies. That's why umatrix handle them like that. I think it's better to use firefox's cookies settings or a dedicated addon for data like cookies or local-storage.
