Thunderbird is a great email client - and Lightning makes it even more helpful.

I would recommend this plugin to every business person, individuals may not find it as useful as businesses.

It can open iCal and Outlook invitations as well, meaning if your friend sends you an invitation, and he uses a MAC, you can still open and accept his invitation.

Great integration, and a wonderful plugin overall - 5/5.
