How to downgrade Thunderbird 12.04 to Thunderbird 11.01.1 on Ubuntu 10.04.4 LTS

Question

On several Ubuntu 10.04.4 LTS systems I've recently upgraded to Thunderbird 11.01.1 to 12.04 via "apt-get update/upgrade". Now my T-Bird menu's drop off un-expectantly; trying to click on "Get Mail" sometimes fails intermittently; and printing is also intermittent. I did not have these intermittent problems before upgrading. How do I revert Thunderbird to the previous release until the developers fix these issues?
