I'm looking for a handy plugin for FF to handle proxies.  It looks like there are quite a fer of them.

What are you hoping to achieve? Something quite innocent, I presume?

Proxy Tool (1.16) is pretty versatile 
Stealthy (1.2.1) will let you pose as a Brit and watch BBC iPlayer   

quite innocent...

Thanks for posting, I'll check them out.  I'm just hoping for some app that makes it easy to label proxies with details and make selections as needed.
