SwitchProxy can switch between multiple application proxy configurations on any computer using the Firefox Web browser. This means it can easily run on Windows, Linux or Mac OS X.
SwitchProxy allows you to activate and deactivate proxy connections from a simple menu. It can also switch through a series of proxies at an interval you specify. (The author of SwitchProxy refers to this feature as support for "Anonymous" proxies, but using this feature does not, by itself, guarantee your anonymity!)
To install SwitchProxy:
- Go to the web page for the SwitchProxy add-on for FireFox:
https://addons.mozilla.org/en-US/firefox/addon/125 - Click "Add to Firefox". The installation process starts, and this window appears:

- If you click on this window, the "Install" button (which is initially inactive) counts down from 5 to 1. Then the "Install" button becomes active.
- Click "Install". The add-on downloads automatically and installs itself. The following window appears:

- Click "Restart". Firefox shuts down and then re-opens.
After you install the SwitchProxy add-on, the Firefox Toolbar shows tools for SwitchProxy:
