Disable pre-fetching in Firefox

Have you been noticing weird cookie-setting behavior while searching google lately? Well, google has decided to avail itself of certain browsers' pre-fetching features which loads the most likely next site in the background. Here's how to turn it off (via mamamusings... read Liz's post to get an idea of why you should care about this) :

1. Type about:config in your browser's location bar.
2. Set network.prefetch-next to false.
