Of course there are some grumbles and upgrades woes going on in the Mozilla forums, but I made the move this evening and everything is gravy. The upgrade instructions (from the Mozilla site) call for deleting everything in the Thunderbird program folder, but I just uninstalled v1.07 first and did a clean install.

Make sure to switch to the default theme before installing. It also doesn’t hurt to disable extensions either. When TB first launches it will search for upgrades to all installed themes and extensions anyway.

I like the new function for detecting “email scams”. It will be interesting to see how (or how well) that works.
