Review for KeeBird by KickMeElmo
Rated 5 out of 5 stars
Works perfectly, zero complaints. Most people thought the devs would abandon this when KeeFox became Kee with Firefox Quantum and Thunderbird didn't switch addon engines, but they split it off into this and kept development active.
This review is for a previous version of the add-on (1.0.2).To create your own collections, you must have a Mozilla Add-ons account.
