Description of problem: 

When starting firefox I get the following error message: "Could not initialize
the browser's security component. The most likely cause is problems with files
in your browser's profile directory. Please check that this directory has no
read/write restrictions and your hard disk is not full or close to full. It is
recommended that you exit the browser and fix the problem. If you continue to
use this browser session, you might see incorrect browser behavior when
accessing security features." In fact, permissions are fine, HD space is fine.

This occurs when I configure SELINUX=enforcing, but not SELINUX=permissive.

I originally posted this to firefox bugzilla as #327595, which was deemed a dup
of #308289. See https://bugzilla.mozilla.org/show_bug.cgi?id=308289
There is no error in firefox 1.5.0.1, but I do get the error under fedora
firefox 1.5.0.1-2.1. Possibly fedora backported the bug from firefox CVS -- the
original poster there saw it in pure firefox 1.6a1 in CVS.

It may be related to x86_64.

Version-Release number of selected component (if applicable):
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.0.1)
Gecko/20060207 Fedora/1.5.0.1-2.1 Firefox/1.5.0.1

How reproducible:
Every time.

Steps to Reproduce:
1. Install Fedora Core 5 Test 2 on x86_64 with SELINUX=enforcing
2. Install Fedora/1.5.0.1-2.1 Firefox/1.5.0.1
3. Start Firefox
  
Actual results:
Above error dialogue. SSL fails thereafter, but normal HTTP works. After error,
Preferences->Advanced->Security->View Certificates will cause firefox to disappear.

Expected results:
Firefox starts without error dialouge. SSL works. View Certificates works.
