[orca-list] Link navigatin broken, and no speed up

[Hermann <meinelisten onlinehome de>]

Hi,
visit any website, for example:
http://www.freedomscientific.com/
Try to use the link navigation keys. You will find that they are
completely broken; the same for visited links.
Latest FF and latest Orca.
Can anyone confirm this?
Note: All other navigation keys seem to work.
And what about speeding up? As others have written, this is not the
case. So what's up with FF and Orca?
Hermann
