The fundamental question, though, is what is causing that page to pop
up?    What OS? (I presume Linux based on this email list, but only
you can answer definitively).    Did it happen when you got the
machine, or recently, or when?

Is it Firefox that came with the OS (if a Linux version), or obtained
from mozilla's web site, or possibly some other source (maybe an
application you have installed it)?   Maybe your ISP made some change
or installed it?

Do your system's event logs reflect when this might have started?

I just as well presume aim to fix problem at the source rather than
trying to place temporary fixes around an existing problem.
