Re: [orca-list] A page that can crash orca

[Alex Midence <alex midence gmail com>]

Don't know if this helps or not but I tried this using Jaws in Windows
and there was no crash.  Firefox continued working just fine.  I also
tried with NVDA but apparently, they don't have it set up to loop back
to the bottom if you hit shift h on a page near the top of it.  So,
it's definitely something on the Linux side of things and how Firefox
interacts with the accessibility stack on that platform.  But then, I
suspect you guys already knew that.

Hope that helps,
Alex M
