Odd firefox behaviour

[Mark Davies <mark%ecs.vuw.ac.nz@localhost>]

With the firefox-3.5.5 package (on NetBSD5.0_STABLE/i386) I'm seeing the 
following.

If you run it via /usr/pkg/bin/firefox everything seems to work fine but if 
you run /usr/pkg/lib/firefox/firefox basic things work but if you try to 
access an https page you get 

"Problem loading page"

Firefox doesn't know how to communicate with the server.
* Check to make sure your system has the Personal Security Manager 
installed.


You may wonder why you would run /usr/pkg/lib/firefox/firefox but if that 
value is not stored in GConf firefox pops up the "Firefox is not the 
default browser" dialog box and if you click "yes" to making it the default 
then that is the path that gets written to GConf.
So you get the situation that if you run firefox directly everything works 
but if something like thunderbird fires it up https fails.

Any ideas how to fix?
