Indeed, some people have problems with firefox using IPv6 if they have a
network connection with only IPv4. But you would see similar symptoms if
you have several default routes where only one is working. That would
likely be a misconfiguration in a manual network setup, but a bug in the
networkmanager could cause it as well. In a terminal type the command

route -n

which should give an output similar to this one:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface   U     0      0        0 eth0   U     0      0        0 eth1     U     1000   0        0 eth0         UG    100    0        0 eth0

If you have two entries like the last line which start with it
is probably the reason for your trouble.
