Hi use FoxyProxy from a lot of time and I really appreciate its features. I usually switch proxy using that "foxy" icon placed on the lower right of the window: you can just right click on it, select the desired proxy and you're ready to do what you want. Fast and simple enough.
It also comes with some good configuration options, too. As I said in title, FoxyProxy is a clever and nice tool, for web testers and other kind of people. Well done Jung!
