[orca-list] Problems in Firefox menus

[Jean-Philippe MENGUAL <jpmengual hypra fr>]

Hi,

Nightly + Orca master:
1. Open the Bookmarks menu or History menu via alt-b or similar
2. Try down key. It seems to work  as if I press enter, I get something.
3. But Orca does not return anything. While i get the contents of the
other menus, this one does not return anything.

Dont know if it is a firefox regression or simple change

Regards
