I used yum install thunderbird and now I have a menu entry to start
Thunderbird. :-)

I noted that on the top of the screen there are a few small icons to
the right of te last menu item, these seem to launch certain
applications which one wants quick access to.
But the email program is not Thunderbird, it is another one entirely.

How can I replace that speedicon with Thunderbird?
