Neither the default filter for dnssearch.rr.com, nor my own variations on it, ever resulted in a blocked redirection. It was a simple test case, googleeeeeee..., and NoRedirect can see and warn of the coming HTTP/Refresh, but doesn't block it. Tested in a clean profile, and inside an existing profile with this addon stack: https://addons.mozilla.org/en-US/firefox/collections/whatrevolution/dissent/

Same result in both tests, except that my Dissent collection is able to block the HTTP/Refresh behavior in other ways.
