Behaves strangely in Firefox when navigating a grid which contains a div surrounding a group of rows. It identifies the grid as a table with 1 row and 3 columns. When arrowing through the grid the cells are identified with their row and column coordinates (but both the header row and first data cell row are identified as row 1). In row 1 (the header row) table commands navigate only that row. In data row 1 (row 2) right/left cell commands jump to the header row. In other cells prev row jumps to row 1 (the header row) and all other table commands produce "edge of table".

(The attachment contains two grids: the first works, the second contains a div for rowgroup.)

Steps:
Load file nvda_grid_with_rowgroup.htm (attached) in Firefox 12. Browse mode should be active with default settings-- including screen layout.
Press "t" twice to move to grid 2.
Actual: NVDA announces a table with 1 row and 3 columns.
Expected: announces a table with 4 rows and 3 columns.
Press downarrow.
Actual: says "column 1 r1c1 column2 r1c2 column 3 r1c3".
expected: says "row 2 column 1 r1c1 column2 r1c2 column 3 r1c3".
Press downarrow to move to the row starting with "r2c1".
Press ALT+CTRL+rightarrow.
Actual: says "edge of table column 1 r1c1".
Expected: says "col2 column 2 r2c2".

This sample was "inspired" by the Dish Network Dish Online program guide which is made from a grid made of divs: the header row is made of divs, the data rows are an unordered list, each row being a list item and the cells are divs. Unfortunately, I think you have to be a subscriber to access the page.

Observed in NVDA versions 2011.3, 2012.2rc1, 2012.2rc2 in Firefox 12.0 on Windows XP SP3[].

This is a bug in Firefox. I will report it to Mozilla if it hasn't been reported already.

It may be a bug in Firefox, but it executes correctly in JAWS 10.0.1178u.

JAWS interacts with the DOM directly and probably does its own table analysis. NVDA relies on Firefox's accessibility API support.
