Rated 5 out of 5 stars

Love this add-on to talk between Thunderbird, Google Calendar, and sync with my iPad/IPhone calendar. This new version adds a time zone feature which did not happen before. I enter something on Thunderbird calendar. Go to iPad to see it there and it has a little note adjusting time to GMT. If I try to change it from there, it is in GMT. I have to go to Google Calendar site, click on event, and "remove time zone" option. Never happened before. Kind of annoying.

This review is for a previous version of the add-on (1.0.2).
