Just installed TB 3.1.20 to import Netscape 7.2 emails and address book, which worked fine. Add-in "MoreFunctionsForAddressBook" was able to load "Imported Addresses" address book from backup. Now I need to bring TB current. How to upgrade from TB version 3.1.20 to current version 31.4.0? Can this be done in a single step or do I need to install interim releases?

I believe you can just update straight from TB 3 to TB 31.

To be on the safe side, you could make a back-up of your profile beforehand.

I have a vague recollection of some significant changes at TB 5, but I don't think they affected the profile.
