rewrite google search result page to link directly to search result url

google-serp.user.js

// Google SERP URL rewrite
// 
// User script will rewrite search engine results page for Google and place real
// links to results rather than links that proxy back via google.
//
// So you go straight to the page when you click and you can copy/paste the link
//
// Install:
//  1. Download to desktop/wherever
//  2. Open Chrome extensions page (Window -> Extensions) or URL chrome://extensions
//  3. Drag+drop this file into the extensions window
//
// Also compatable with Firefox + Greasemonkey
