This question already has an answer here:

I'm trying to use Thunderbird again, but I can't make it use Firefox to open links. I'm using KDE and Firefox is my default browser. I tried the network.protocol-handler method but it doesn't work.

To open links in thunderbird so that they will open firefox or chrome or opera, you open preferences, attachments, and click on use other and navigate to the browser that you want to use.

I have already tried that, but there is nothing to select. – lovinglinux Oct 21 '10 at 14:21
I'm accepting this answer, but I decided to use Opera for mail, instead of Thunderbird, so will no longer testing other options. – lovinglinux Oct 23 '10 at 0:47

It seems that thunderbird uses sensible-browser, that actually tests for the following alternatives: gnome-www-browser and x-www-browser; so what you need to do is manage your altenatives with:

sudo update-alternatives --config gnome-www-browser
sudo update-alternatives --config x-www-browser

And the choose Firefox for those.

Probably you'd only need to update x-www-browser since you're using KDE.
