How to have Mozilla-T-bird automagically bring up webpages?

[Terry Egan]

Hello,
	I loaded a brand new copy of Kubuntu 5.04, changed my /etc/apt/sources 
to breezy, did an apt-get update and an apt-get dist-upgrade and rebooted.
	Then I did an apt-get Firefox and Thunderbird and set them up ( I 
thought ).  However, clicking on a hyperlink ( http://whatever.com ) in 
TBird does not bring up Firefox, or if Firefox is already displayed, 
does not change the displayed webpage to http://whatever.com.
	Can someone tell me how to modify the behavior of whichever program so 
that I can just click on a hyperlink in TBird?
Thanks
