The Thunderbird bug has been fixed. It already supported webcal urls, but had a problem when a webcal url ended with .ics as it did in your case. That problem is gone now.

Back to the problem: Firefox should open those URLs with thunderbird.
I think that Firefox on Ubuntu should provide the defaults that it does, and not require me to register something.
