Rated 1 out of 5 stars

After installing add-on my thunderbird didn't start again and I had to cancel the process.

Second try worked but couldn't find any button or hint how the add-on works. Did a test with new calendar entry but couldn't find the entry in Google Calendar.

For now the add-on doesn't do what it promises.

This review is for a previous version of the add-on (4.4.2).
