Since the update to 78.11, Google synchronization no longer works. I have been using Thunderbird for 15 years but this point is so crucial that I will have to change my email client with sadness. Thank you by advance to the teams for making sure to keep the best compatibility after each release.

The integration with Google Calendar is crucial for me. Thank you for this great project!

Does not work with Thunderbird 78.11.0 (64-bit). It worked quite well before my latest update.

Ce module ne fonctionne pas sur mon ordinateur, W10, TB 78.11. Pas de connexion, pas de synchro.

No funciona más con Thunderbird 78.11.0 (64 bits). No permite escribir eventos, ni sincronizar los creados.

Great add-in, and easy to use. I am using it both in Windows and Linux.

Recently, this add-on does not allow me to invite others to the event.

Was great but on 78.10.2 I cannot accept invitations in google events.
It says "No writable calendars..."
I checked mozilla support and one option calendar.google.enableEmailInvitations which is supposed to turn it on is not available in the .config

Great Addon. It worked perfectly but since last TB update I can't create, delete and update events in TB (Addon 78.0.1, TB 78.10.2 32-bit, Win 10 64-bit). Looking forward to a solution.

There is a solution: https://github.com/kewisch/gdata-provider/issues/77 Scroll down to July 25th 2020
In short words : use CalDav instead of the addon.
Make sure that you replace the @ in your email address with %40 in the CalDav-URL
AND make sure you allow Cookies in Thunderbird.
That worked for me, incl two-way-sync for the main google calendar. I removed the addon Provider for Google Calendar after doing these changes.
Some more details, if you have configured your Google calendar to show additional calendars (like bank holiday calendars etc.) or you need Google task integration: that worked for me as well, but only WITH Provider for Google Calender installed. When I had the addon still installed and at the same time configured CalDav for the same Google calendar, the provider-for-google-calendar-addon did come up with the standard login dialog, afterwards I could see the additional calendars in Thunderbird. The CalDav-integration without the provider-addon didn´t show the additional calendars. Maybe you want to do some more testing re CalDav PLUS provider-addon, but as I only needed the main calendar, I stopped after that worked and de-installed the provider-addon.

Like others, I'm disappointed to find that Google calendars aren't visible and I must manually hide/show each individual calendar to have them show up.

Hopefully this has been raised as a bug/issue and will be fixed in the next update.

Works great except one thing: When I start Thunderbirds, all my Google calenders are hidden. I have to hide/show them manually again to make them visible. Hopefully there will be fix for that soon.

Yesterday it worked perfectly today no google calendar is popping up. ;-(
Hopefully an update coming soon. Would also be great to have this add-on as a standard in TB. ^^

Looks like the TB update to 78.10.0 broke the add on again. Dialog to authenticate never populates.

This user has a previous review of this add-on.

addon 78.0.1 works fine with TB 78.7.1 and my Google calendar and tasks.
