I guess you are talking about keyboard browsing, aren't you?
That's not clear from the bug sumarry.

Otherwise, the title of a table is reacheable through type as you find.

bug 245142 is probably a dupe, marking dependent for now

the probably root cause of this is that the outer table frame has a caption and table frame which play the roles of line 0 and line 1 for this frame but does not have a separate line iterator interface.

Comment 8 is bogus

The problem is nsFrameIterator::GetFirstChild will never return the caption as they live on a additional childlist. So it will always return the inner table frame which  is the first child on the primary child list. Now comes the question how much special casing can we tolerate at this interface. 
The next question is when to return the caption a a first child
1. top caption
2. left caption for a ltr table
3. right caption for a rtl table

Aaron:

How much performance loss is acceptable for this inside nsFrameIterator::GetFirstChild as we need to query for every frame if it is a outer table frame.

The other functions need the same special casing.

Should we take the risk for 3.0, is it really worth giving the number of captions on the real web?

As far as I can tell, it's not worth it for Firefox 3. I've not heard that this is a major problem. The one place it might be is the Orca screen reader, which relies on care browsing. However, te text of a table caption is also available through the accessibility interfaces, and can be announced as a user enters a table.

Ginn, as far as you know do we really need this for Firefox 3?

I think it's not blocking Firefox 3.

The fix needs to consider left/right arrow, up/down arrow, caption position to the table, and the direction of the table.
In Sun Mozilla 1.7, we had a hack for left/right arrow, we considered caption position, but not the direction of the table. I think it's not very helpful.
