Simple and effective. One thing to improve : I have to restart my browser every time I change the proxy with button :(
My FF version : 5.0

This review is for a previous version of the add-on (3.0.2.1-signed.1-signed).

This happens when you use more than one proxy addon at once. Please uninstall/disable other addons when use guifiproxy.
