firefox 58, orca and 16.04

[Tom Masterson]

I need suggestions on where to look.  Firefox on my system stopped working 
with orca after the last update (no setting changed) and my wife tells me 
that it is working properly as far as sighted people are concerned.  All 
other applications that I run from the desktop appear to be working 
correctly with orca (not that I run many).  I have found a couple of 
people on the orca list who are not having an issue with firefox, 16.04 
and orca.

Any help will be much appreciated.
