Hello again,

LOL! You're a noob??? I've only been using Linux for about six months
now, after years of suffering the problems of Windows... I have been
tearing into the guts of Ubuntu every day however, and have been
learning quite a bit.

Also, I'm pretty good at using Google, and a search there on "ubuntu
thunderbird http link" has put me onto a thread that contains what I
think may be the answer for you.

Create a text file and name it user.js and put the following lines in it -

user_pref("", "/usr/bin/firefox");
user_pref("", "/usr/bin/firefox");
user_pref("", "/usr/bin/firefox");

Then save into your Thunderbird profile folder. The right folder will
already have a file called prefs.js. On my machine this path is

WOOPS! I realized right after clicking the Send button, that I had 
forgotten about your non-standard path to Firefox. Please amend the 
paths in the user.js file to "/usr/bin/firefox-3.0" to make it work on 
your system.

I hope this solves your problem.

Later, Ray Parrish
