Rated 4 out of 5 stars
A nice and minimal Add-on for people who often have to change their proxy settings.
But i have 2 things which could be improved:
1.The Icon should be placed near the adressbar.
2.It would be cool if you could quick edit the proxy settings on middle click.
Toolbar option will be available shortly in version 1.7 for Firefox. You can edit the proxy settings by right-clicking the icon.
