Review for Provider for Google Calendar by Munich_Mule
Rated 1 out of 5 stars
Is this add-on still maintained?
It does not work since at least 3 months (Thunderbird version 52.2.1).
At the sign-in step you can not log in to google. The "next" button just has no effect.
(I will change my rating back again, if it this is fixed. When it works, I relly like this add-in.)
