[orca-list] Firefox caret issue

[Rob Whyte <fudge thefudge net>]

Hi,
I hope that I am able to explain this problem and someone will know the
reason for what is happening.
Let me start by saying I am running Orca master and am up to date with
atk at-spi2-core at-spi2-atk git repo's as of yesterday.

Since I started using the next Ubuntu LTS Trusty 14.04 I have had
Firefox issues.
I will open a link in a new tab or window, when I close that window or
tab and continue on the page I originated on I lose functionality with Orca.
To be precise, Control Insert Space still brings up Firefox preferences
for Orca.
Yet the navigation keys do not work, i.e H B E etc.

The solution to fixing it until it next happens is to hop in to Orca
settings with Insert Space and choose the OK button.

Then the functionality is restored.
First I thought it was Unity related, so I have spent a couple of weeks
in Gnome-shell, it still occurs.
As mentioned above upgraded other a11y technology with same results.
My next step is to try vanilla Gnome on Arch, if Arch users have the
same bug crop up my only conclusion is that it would be Orca.

Any feedback or similar bugs would be welcomed.
I have captured this in a debug file but I could not really figure out
what went wrong.

Kind regards
Rob Whyte
