I keep getting asked for server username and password

: Function ereg_replace() is deprecated in /mozdev/sandbox/php/include/globals.h on line 95.

I recently upgraded to FoxyProxy Plus and now when launched firefox get asked for username and password everytime. Can anyone help as I thought with Plus this didn't happen

Are you sure you properly

Are you sure you properly deinstalled FoxyProxy Basic and activated the Plus version?
