Firefox problem, FreeBSD 5.3

[Jim Johnson]

Hey all, I'm having an issue with Firefox.  When I go to run it
nothing at all happens.  No error messages are displayed and no
browser window pops open.  This makes is pretty hard to troubleshoot
anything.  Does anyone have any suggestions as to what I could try? 
My ports are fully up-to-date as of about 20 hours ago and it built
without a hitch.  If this is the incorrect forum for asking such
questions, please educate me with the correct e-mail address.  Thanks!
