Windows only: All-Glass Firefox v2 extends the super-slick Windows Vista Aero transparency effects to almost every piece of the Firefox interface.
After installing the add-on and restarting your browser, you'll be greeted with shiny new transparency effects similar to the Aero Geek Firefox customization, but covering the entire window chrome. The similarity is no accident—All-Glass Firefox is based on the same Glasser extension that we used in the previous customization, but takes it a step further, even adding fancy text effects if you are running the latest beta of Firefox.
All-Glass Firefox is a free download, requires Firefox on Windows 7 or Vista. For more, check out the Aero Geek Firefox customization for a productive browser with slick transparency effects.
