I am planning to use the Accessible Rich Internet Applications (ARAI) 
techniques that allow me to identify the tabs.  Using the ARIA techniques 
and running with JAWS or Window-Eyes in Firefox will identify the tabs to 
the user.

When you are navigating a page in Firefox with ARIA implemented, using 
JAWS virtual pc cursor mode off or Window-Eyes browse mode off will allow 
you to navigate using the arrow keys.
