[orca-list] Orca and firefox

[Max <heavy9922 gmail com>]

Hi, all.

I found a problem in the "orca" in "firefox". In order to reproduce this 
problem, you need to go to the website:

http://7ba.ru/ex/catalog/166/

And then - to use the key combination "shift + a".
"Orca" does not move to the previous object to press.

This problem - not a regression. It has been observed for a long time.
