thunderbird no longer opens clicked URLs in a web browser (protocol-handler.app.http) ?

[Lonni J Friedman]

Ever since updating to thunderbird-3.0beta3 (in Fedora11), any URLs
that I click on fail to do anything.  Previously they opened up in
Firefox.  I've got the following set in thunderbird:

network.protocol-handler.app.http;firefox
network.protocol-handler.app.https;firefox
network.protocol-handler.app.ftp;firefox

Anyone else seeing this problem?
