There has been some confusion as to what is the most current version of Thunderbird. Thunderbird 8.0 released on November 8, 2011 is the most current version of Thunderbird. Mozilla did release an update for Firefox (8.0.1) on November 21st, 2011. However, the issues that were addressed in this update (older version of RoboForm caused browser to crash on start-up and crashing issues with JAVA heavy sites on Mac with Firefox 8.0) were related to Firefox only. Therefore Mozilla did not do a Thunderbird 8.0.1 update. At this time it does not appear there will be any other Thunderbird updates until the next scheduled release of Thunderbird 9.0 on December 21st, 2011. In addition, looks like the omni.jar changes are on hold currently and are targeted for the Thunderbird 11 release on March 13, 2012 (this version goes to the Daily channel around December 21st).
