Very simple, no-frills add-on that lets you toggle from "direct connection" mode to "manual proxy" mode and vice versa with one click of a button.
Useful for people who uses multiple networks at work, for example wireless connection with direct internet connection and local network that connects to internet through a proxy. No configurations or proxy settings needed; this uses the original proxy settings of your browser. -----------------
You can add the button to the standard tool bar. When you click on the button it toggles between proxy mode and direct connection.
