Anyone used this? Its not an official release. I was using the official one 1.5.02, which isnt UB yet. Managed to find the UB Beta one (http://ftp.mozilla.org/pub/mozilla....ozilla1.8.0/thunderbird-184.108.40.206.en-US.mac.dmg) - there are talks of a Profile Migration issue, what exactly does that mean? Ive installed it anyway and its so much more faster then the PPC under Rosetta one. Everything seems to be ok - my emails are all still there etc - backed up just incase tho Anyone else running this UB version?
