Early Adopter Download of the Day: Firefox 2 Beta - Lifehacker: "Brad says:

You don't even need to install an extension. Just type 'about:config' in the address bar, right-click within the list of preferences and choose 'New String.' Call the new preference value 'app.extensions.version' and give it the number (e.g., 1.5.0.4) of the version you want extensions to think you're using.

When you install an extension, it will look to this preference value (if it exists) rather than your actual version number when it's checking compatibility."
