This is NOT the full blown version of my Firefox eXpress package (Windows only) which can be found here.
This is just the XPI file from the Firefox eXpress package... this file will automatically install all of the extensions and themes that I have in Firefox eXpress.
Save it to your desktop.
Open Firefox... drag the XPI into the Firefox window and click the "Install" button.
Turn off any extensions you don't want to use.
