It seems that works with thunderbird 68, but still have some problems. If you have many google accounts it is not switch from one account calendar to the other. Instead open the new calendar to the browser...

This is a GREAT add-on and I've been using it for years in stead of Lightning, which is simply not great. Now that I've upgraded to Thunderbird 68, this no longer works. Can this please be fixed for the new version?

This is a great concept, and almost exactly what I need. However, I cannot get Tasks to work. They open for a second and then disappear, and I'm unable to get them to open again. Using Thunderbird 68.3 on Windows 7. Once Tasks work reliably, I'll gladly give 5 stars.

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.

Previously worked perfectly: On first use you should see the Google Calendar login page. When you login you
will be prompted by a notification bar which can save your username and password
for the site.

But the above no longer applies seem to have to login each time.

Previously, I used the now defunct Google Calendar Tab. This is a worthy successor, and the most important Thunderbird extension for me.

Thank you!
This is the simplest yet most useful integration of Google Calender in Thunderbird, showing you not only the calendars, but also Google Notes and Tasks!

I've been mucking around, on and off, for years, making sure that my online and offline calendars are synchronised. Now they are, thanks to your Open Google Calendar extension. I also have the same issue (it's not much of an issue, really) with Google Contacts. Do you fancy writing an Open Google Contacts Add-on? :-)
