Rated 5 out of 5 stars

Dear Keychain Integration: Thanks very much for your great add-on! This review is specific to OSX (10.7.5 Lion) and (surprisingly), the SeaMonkey browser/email-client. This (IMO) is the "best", most secure browser/email-client going (uses current software version of FF/TB). But the problem in OSX is that FF/TB and SeaMonkey won't integrate with the OSX Keychain for passwords. With Keychain Integration 1.1.8, the "Keychain" works perfectly! Julian Fitzell, please add your wonderful add-on to the SeaMonkey Add-ons, and again: thanks so much for your add-on! This is an important security improvement in OSX.

This review is for a previous version of the add-on (1.1.8.1-signed.1-signed). 

Hmm... it seems like only Firefox compatibility gets updated automatically with each new release. I've updated Thunderbird and SeaMonkey compatibility to the latest versions—haven't actually tested it, though, so hopefully it stil works! :)
