This is a great piece of software. I used to work for a company that blocked sites like YouTube. This was extremely frustrating, since many of the software websites I'd visit would embed relevant YouTube clips or tech talks. I was able to use FoxyProxy to tunnel any requests to YouTube.com to my home network. This meant that the blog post was fetched over the work network and the embedded YouTube clip was fetched over my home network. It all worked very well.
