It does what it claims: opens the google calendar web page in a Thunderbird tab, and allows you to interact with the calendar in exactly the same manner you would with a web browser.

I started using this add-on only a month or so ago, when the "Provider for Google Calendar" add-on inexplicably stopped working for me; it repeatly asks to authenticate with google, but never manages to do so. "Open Google Calendar" filled the void, but unlike Lightning, only supports google calendar.

In late November, Open Google Calendar stopped working with the latest version of Thunderbird. I reverted to Thunderbird-60 and OpenGoogleCalendar-1.4 to continue access to my calendar in Thunderbird. Today, Ubuntu updated Thunderbird to version 68; lo and behold, Open Google Calandar still works! Checking the Thunderbird Add-Ons tab, it claims to be disabled, but it still opened up when Thunderbird started and appears to be fully functional. Go figure.

If there's one thing that prevented my giving 5 stars, it's that updates don't come in a particularly timely manner. But it's working, so I'm not complaining. Much.
