Review for Contact Tabs by Markusrow
Rated 5 out of 5 stars
This Add-on makes using multiple address books so much easier. It enables search across all address books in one step. I have many address books, (more then 10) Some categorize for aspects like sport, personal, country, business etc. Other competing aspects are whether a contact should be synced to certain devices at certain stages, like when traveling. While emailing, I cannot immediately recall where a specific contact was stored, nor why.
This review is for a previous version of the add-on (0.8).To create your own collections, you must have a Mozilla Add-ons account.
