Assert error from Latest Firefox (just update)

[Richard England]

Yum updated to Firefox this morning  (firefox-3.0.6-1.fc9.i386)  on my 
F9 system (fully updated) and now I'm getting a dialog box that shows 
the following info every time the  browser is started.   The browser 
comes up but throws this assert.  My error or there?

Thanks,
~~R
