A newbie question to firefox users out there

[Krister Ekstrom]

Hi and sorry for the cross posting.
I understand that blind Ubuntu users use Mozilla Firefox with at least
moderate success with Orca. I have tried the Firefox that comes with the
latest Edgy, Bon echo beta 2 and on pages that don't contain tables or
frames or forms, things seem to work very smoothly, however on pages
with tables, forms, frames etc the cursor tends to get stuck and either
i hear the same line spoken over and over or i don't hear anything at
all. Has anyone else the same experience or is there something somewhere
in Gnome, Firefox or elsewhere that needs to be changed?
Thanks for any help.
