[orca-list] Reading Line by Line in Firefox

[Steve Holmes <steve holmes88 gmail com>]

Allow me to describe the situation here and I wonder if others are
experiencing anything similar.

1. Go to one or more pages with Firefox 5 and generally knock around
in there, surfing from one page to another.

2. At some point, pressing up and down arrows go silent but arrowing
left or right will still speak a character at a time.  Also, other
structural navigation keys go silent too.

The only fix for me is to restart Orca.  As soon as Orca restarts, all
proper navigation works again.  I've had this happen several times in
a given gnome session.  I'm using recent git pull of Orca Master and
gnome 3 plus Firefox 5 from Arch Linux Repos.

Can anyone else duplicate these problems?
