Hi John,
Since Firefox is accessible on Window/Linux and Webkit is accessible on the
Mac, it would follow that accessibility would work just fine.
However, if there is a doubt, at least on the Mac, Eclipse's start up screen is
done in the SWT brower, if I am not mistaken.
That may be a way to test this out for accessibility.
Regards,
Alex,
