It saves you a few clicks when switching proxy connections, but this Firefox toolbar add-on does seem to take up more space than it needs. Installing Proxy Toolbar is easy, but the toolbar's value boxes take up only a small part of the full window width toolbar, and the bar can't be shortened or placed with other toolbars.
The toolbar simply lists the proxy set found under the Firefox options, saving users a few mouse clicks. This tool saves navigating through the Options menu to enable or change proxy settings. In addition, turning on or off the proxy takes just a single click in the Use check box. Changing proxy settings is also quickly accomplished by entering proper values in the toolbar text boxes.
Experienced users will find Proxy Toolbar makes it easier to set and use proxies. This is a toolbar that users will want available even if it isn't always enabled.
