Whoa, I just realized that I totally misread your question! Sorry if i insulted
you with newbie info. I have no idea how the kernel would select an interface
if both were on the same network.
Sorry, *duh*, I'll go drink some more coffee now...

That's not taken care of by Mozilla, rather by your routing
setup.
Check out the output of:
netstat -nr
That's your routing table. By default, when an interface comes up on an
IP, an interface route is added through that interface for that IP
network - so if your eth0 came up on 10.0.1.2/24, you'd see a route in
there for 10.0.1.0/24 through eth0 - then there is the default (0.0.0.0)
route. That's usually the route that matches any network that is not
directly connected. So if you had a default route through say 10.0.1.1,
your internet traffic would want to be routed thru 10.0.1.1 - to get to
10.0.1.1, IP knows that it has to use eth0, so the traffic goes out eth0
destined for 10.0.1.1.
Or maybe you're just asking about where the NIC's get configured? That
info is in /etc/sysconfig/network-scripts - check out ifcfg-* in that
directory. Also, your default route is set by the GATEWAY entry in
/etc/sysconfig/network.
Hope this helps!
