Rated 5 out of 5 stars

As the previous reviewer mentions, reminders are not working properly with this latest build for any calendar synced with google. There is also a 10 minute default reminder which cannot be removed -- although at the moment it is unclear whether this is a google issue or a thunderbird or a provider issue. all i can say for certain is that the 10 minute reminder cannot be removed from google calendar's site even with thunderbird disabled -- this however could still be caused by provider giving google a corrupted reminder of some sort.

Further information -- I can confirm that a newly created calendar does not face this issue -- there is something wrong with reminders on shared calendars -- and it may very well have nothing to do with provider access. I can also confirm that if you move an event to a non-shared calendar, the default incorrect reminder goes away.

This review is for a previous version of the add-on (0.5).
