I have:
   Configuration->Preferences->External programs...
        /usr/local/bin/firefox/firefox --new-window '%s'
   ~/.mailcap
        text/html; /usr/local/bin/firefox/firefox --new-window '%s'
and the "Open with" dialog still intrudes, asking if I want to use
        /usr/local/bin/firefox/firefox --new-window '%s' 
when I hit "O"...  

Surely /etc/mailcap containing this RedHat default:
        text/html; /usr/bin/xdg-open %s ; copiousoutput
is not forcing the dialog asking if the above 2 overrides is really what
is wanted...

Thanks,
Pierre
