Reload settings from user profile for Firefox and Opera

[PHP6]

Hello,

Is there any way to force Firefox and Opera internet browsers to reload proxy settings from user profile? (except restart)

BTW I have successfully used WinAPI function to make Internet Explorer reload proxy settings.

Thanks in advance

p.s. I am ready to pay for working solution
