There is still a problem with version-3.0.3 : I have to restart my browser every time I change the proxy with button.
I only use one addon at once. I haven't this problem with version 2.5.

I could not reproduce your problem. Which firefox's version do you use? Do you try it with a new profile? Please contact me by mail ("Support E-mail")
