Have you noticed the new Google search favicon? I am not sure if Google intends to keep it forever but I like the refresh. You can update the Firefox’s default Google search plugin to show the new Google search icon: Locate the searchplugins folder in your Firefox install folder. (typically C:\Program Files\Mozilla Firefox\ on Windows).
