Rated 4 out of 5 stars

This is great and works like a charm!!!
One issue thou: Using FF's own "problem loading page" will get a lot of users confused. I'd suggest a "NoRedirect is right on the spot" screen instead, displaying the URL originating the redir and the rule matched.
Anyway: thumbs up from me!

This review is for a previous version of the add-on (1.2.4).
