[orca-list] Firefox 6 (with Aria improvements)

[Jason White <jason jasonjgw net>]

In the release notes of Firefox 6:
https://developer.mozilla.org/en/Firefox_6_for_developers
it is mentioned that several Aria bugs were fixed. See the above reference for
the details.

The change in the behaviour of textarea fields is also notable, as this may
affect Orca users.

Firefox 6 is in Debian Unstable already (I'm downloading it now) and it may
be released soon in other distributions that have a rolling updated policy.
