[orca-list] Getting about:performance working

[Nolan Darilek <nolan thewordnerd info>]

Firefox performance went batty on me this morning, so I went searching 
for a Chrome task manager equivalent and found about:performance. This 
partially worked, though I couldn't seem to navigate to all my tabs, and 
repeatedly had to tab out of and back into the window.


I'm wondering if about:performance is routinely replacing its table and 
Orca is losing its position? If that's the case, could Orca somehow grab 
the row with which it is associated, then return to that particular row 
or something near enough? For instance:


 * I launch about:performance and start navigating to the table. I 
arrive at row 4.

 * Firefox refreshes the table, so suddenly Orca loses its original 
position.

 * Orca returns to row 4 and, if I'm lucky, the table column where I 
left. So even if the table itself refreshes, Orca maintains a consistent 
position in the table.


I don't know if this is what's happening, but if I'm returned to the 
original position, at least I'll get a relative snapshot of what items 
are in the table, even if the items move around a bit. Usually, in the 
case of performance monitoring, that's good enough to give me a sense of 
what occupies a given slot and is stealing resources.


Thanks.
