FoxyProxy

FoxyProxy is an open-source, advanced proxy management tool that completely replaces Edge's limited proxying capabilities. No paid accounts are necessary; bring your own proxies or buy from any vendor. The original proxy tool, since 2006. FoxyProxy has been owned and developed consistently by the same team since 2006. It has never been sold and never will.

WHAT IS IT?
FoxyProxy is a browser extension which switches an internet connection across one or more proxy servers:

1. by point-and-click of colored icons
2. by URL (define URL patterns with wildcards or regular expressions)
3. by browser tab - set individual proxies per tab: assign up to 4 proxy servers for use on 4 different tabs.

FoxyProxy automates the manual process of editing your browser's proxy settings.

* Customize colors and country flags to make it easy to see which proxy is in use
* Proxy per tab, by URL, or by point-and-click of colored icons
* Import/Export all of your settings, or just URL patterns, to share with others (fixed in 8.0 and above)
* Select a proxy specifically to use in Incognito Mode
* Keyboard shortcuts
* Globally exclude any domain from proxying
* Create patterns with wildcards or regular expressions. A pattern tester is included.
* (optional) Automatically synchronize all of your proxy settings with your other browser instances when you use Sync.
* Turn WebRTC on/off to further limit discovery of your IP address
* Built-in predefined selections for tor, privoxy, and psiphon
* Extensive built-in help
