Rated 4 out of 5 stars

A great plugin, especially when combined with the "More Columns for Address Book" plugin!

The ability to synchronize with Lightning Calendar is also a huge bonus. (Personally I find the "big list" of birthdays useless)

Enhancement: I have a lot of contacts, and for a lot of them I might know their birth date, but not really care to be reminded about it. Perhaps the ability to have Birthday Reminder choose a "subgroup" (user specifiable) to get it's reminders from might be better? (i.e. I might have a group called "Friends" and "Family" where I'd get reminders, however the group "Acquaintances" I don't really care to see reminders.

This review is for a previous version of the add-on (1.0.4.2).
