Hi,
Could you add web blocking /ads blocking (analyze and filter get/post urls) with support of mains filter list like filterset.g, adblock etc...
My old agnitum firewall supported that (by plugin).
Please, don't answer It's a browser problem

...When you use more than one browser and you have to maintain plugins, list subscription...
It's better than dns blocking and proxy, that's fine grained, system wide and maintenance less (with subscription to downloadable updated lists).
Thanks,
Alex
