[orca-list] Help debugging Firefox focus tracking

[Bill Cox <waywardgeek gmail com>]

I think the most significant bug right now is that structural
navigation in Firefox 3.6 is somewhat broken.  Joanmarie filed this
bug report:

https://bugzilla.mozilla.org/show_bug.cgi?id=546068

To test this bug, I call acc.queryText().setCaretOffset(0) in
accerciser.  I would like to single-step through the code this calls
to see what happens both before and after the bug was introduced in
Firefox.  Does anyone know how to do this in Python?  Is it possible
to do within accerciser?

Thanks,
Bill
