Firefox and Thunderbird are upgraded to the latest release in all stable Ubuntu releases, so there's no need to upgrade to 12.04 to receive a fix in a later version. That bug is very old and 10.04 has had that "fix" for over a year now with the Thunderbird 3.1.x series. If this is still affecting people, it must be a different bug.
