Elite Proxy Switcher for Firefox does exactly that. It docks itself as a little status bar at the very bottom of the firefox window where it'll either say Direct Connection if you're not using a proxy obviously or it'll show the IP of the proxy you're currently using. You can just click it once to switch back and forth. Right click to change the IP.
