FC12-- Temporarily turning off IPv6 in Firefox and Thunderbird

[Robert Moskowitz]

I am at the IEEE 802 Emergency Services Study Group meeting and IPv6 is 
configured on their wireless and not working, so to sites like IETF and 
my home, I am getting long time outs until Firefox and Thunderbird give 
up and then try IPv4.

How do I change things that for this week, I skip the IPv6 attempt?

Oh, and next week is IEEE 802.15 Interim that will probably also not 
have IPv6 configed right, and the week after that is IEEE 2030 which, 
well I just don't know...  :)  IEEE month for me!
