Butler
Mark Pilgrim released Butler, a ‘user script’ designed to run under the Mozilla Firefox Greasemonkey extension. Among other things, Butler strips ads from Google search results. I suspect we’ll be seeing many more Greasemonkey scripts – terrific idea – giving us all a little more control from web/media gone wild.
It’d be nice if the script could be modified to allow a single edit for the top-level domain Google is using – here Google always defaults to google.ca even if I initially visit google.com. In the interim, I hacked the script for my purposes: butler_ca.user.js
