As we had reported last night, the next build was going to contain a patch to fix the issue with mozglue.dll error message. After installing a fresh copy of the 2012-01-28 Earlybird build, everything is working again. Users will need to update manually to the newest build of Earlybird by downloading and installing a fresh copy from Thunderbird Channels page. There is no reason to uninstall the prior build, simply just install over with today’s build.
