FoxyProxy 3.1 (Windows)
FoxyProxy is an advanced proxy management tool that completely replaces Firefox's proxy configuration. It offers more features than SwitchProxy, ProxyButton, QuickProxy, xyzproxy, ProxyTex, and TorButton. Features include but not limited to an animated statusbar/toolbar icons show you when a proxy is in use; define which proxy to use (or none!) for arbitrary URLs using wildcards, regular expression, whitelists, and blacklists; define multiple proxies and order their use with priorities; no more wondering whether a URL loaded through a proxy or not. FoxyProxy includes an optional log of all URLs loaded, including which proxy was used (if any), which pattern was matched, timestamps, etc; temporarily or permanently disable a proxy with the click of a button; out-of-the-box support for Tor - zero configuration; optional status bar information about which proxy is currently in use; full Proxy Auto-Config (PAC) support, with PAC features not available within Firefox itself; and unobtrusive presence, stable execution, premier support.
