better WHEN it has its own site of rules (like userscripts.org) Rated 5 out of 5 stars

Mason needs a site setup where people can download scripts by more talented people. GreaseMonkey already has UserScripts.org

RegEx is not everyone's favorite. Mason would do well to have an optional, simple, wildcard mode.

This review is for a previous version of the add-on (0.3.7.4).
