Not as full-featured as its Google Chrome counter-part, which has crossed the version 1 boundary and it seeing development still. But it did exactly what I needed it to do: temporarily spoof my X-Forwarded-For header in order to test a load balancer service I was working with.
For people who just want to set a static temporary value for their X-Forwarded-For header, I would definitely recommend this plugin.
Fifth star ready for the taking, if the latest version was to be pushed to AMO.
