good program for proxy flipping

hey, i just downloaded proxy switcher today from their website (standard version).

it seems like a pretty gay program - only affects the settings within IE?

I wanted something that would affect firefox as well, and also support other cool stuff like testing, lists etc.

Any suggestions?

I'm looking for a proxy flipping too. But the only one I can find it IPRental. It costs about $100 a month for the Premium membership which will allow you to change ips on Mozilla as frequently as you want.

why not get, packetflip and then download proxy firewall??
Thats what i am doing
