[orca-list] Navigating in Firefox

[Merrill <merrill louise gmail com>]

Hi all, I'm new to the list, new to orca and new to ubuntu so it's been
a lot to begin to learn. I've been using screen readers from before PCs.
I'm coming from a Windows environment and screen readers which work
there. I'm wondering if there are commands in firefox to navigate by
heading, find the next button or the next text. If this is documented
somewhere, feel free to point me in that direction. Otherwise, I would
appreciate some hints. Thanks.
