[JBoss-dev] Thunderbird/Firefox integration issue

[Scott M Stark]

Selecting an http link from within thunderbird is not opening it up in 
firefox on my new rhel4 box:

Thunderbird version 1.5.0.5 (20060719)
Firefox version Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.0.5) 
Gecko/20060726 Red Hat/1.5.0.5-0.el4.1 Firefox/1.5.0.5
[starksm at succubus ~]$ uname -a
Linux succubus.starkinternational.com 2.6.9-42.0.2.ELsmp #1 SMP Thu Aug

Anyone know what setting controls this?
