Hello,
I have followed the instructions for the Firefox 3 add-on and I can confirm it IS installed and Enabled. However, when I select a working proxy IP and connect to it via EPS, then return to my browser...nothing is different. It still says "Direct Connection" in the bottom right corner. Also, when I visit the "What is my IP" link, it shows my provate IP address and not the proxy I am supposedly connected to.
All in all, I would say that this is not interacting with Firefox at all!
Is there a fix please?
