Hello,
I upgrade my UBUNTU with 11.04 and have now TB 3.1.15.
Birthday Reminder 1.0.6.5 seems no compatible.
Regards.
Alain

Alain,

the Thunderbird Version 3.1.15 is quite old - please update to a current version, or use version 1.0.5.2 of Birthday Reminder (see https://addons.mozilla.org/de/thunderbird/addon/birthday-reminder/versions/)

All the best,
Sebastian
