Great add-on. Soooo useful. However when I try to disable a specific url pattern inside an active rule, the enable check box remains always checked no matter what. Any ideas why? Tried on 4.0.2 ver.

This review is for a previous version of the add-on (4.0.2). 

You probably got hit by the same bug mentioned here: http://forums.getfoxyproxy.org/viewtopic.php?f=4&t=767. It'll be fixed in the coming FoxyProxy version which should be uploaded to AMO next week.
