FoxyProxy is an advanced proxy management tool that completely replaces Firefox's proxy configuration. It offers more features than SwitchProxy, ProxyButton, QuickProxy, xyzproxy, ProxyTex, TorButton, etc.
FoxyProxy is a Firefox extension which automatically switches an internet connection across one or more proxy servers based on URL patterns. Put simply, FoxyProxy automates the manual process of editing Firefox's Connection Settings dialog. Proxy server switching occurs based on the loading URL and the switching rules you define.
Animated icons show you when a proxy is in use. Advanced logging shows you which proxies were used and when. QuickAdd makes it a snap to create new URL patterns on-the-fly. FoxyProxy is fully compatible with Portable Firefox, has better support for PAC files than Firefox itself, and is translated into more than 25 languages.
