Btw. I just successfully installed the version 128.0.0 - which syncs without problems...
So - I deactivated the automatic update for this add-on and will keep an eye on the page for the add-on manually waiting for the bug-fix.

This review is for a previous version of the add-on (128.5.1).

I can also confirm that since the update on 18.,03.2025 the sync with google does not work anymore rendering this add-on rather use-less.
But the accusation in regard to the donation-request seems rather drastic to me.
Has anyone payed and through that recieved a working version of the add-on?
If that's indeed the case - then I guess the accusations are spot on, since we're talking about a very unsavoury way to change over to a fee-based-service instead of a free-of-charge community-contribution.
But - as I havent't paid anything myself - I cannot say one way or the other.
I only hope very much, that the developer is just trying to get the bug fixed and will present us with a working version very soon!
That would be an incentiv to send a donation his way!

I really liked your add-on, since I need to synchronize multiple Google Calendars with Thunderbird, but since today I cannot get it to work at all anymore... :(
The existing calendars all showed up with connection-problems and when I foolishly deleted them in order try and to set up new clean connections I could not get one calendar set up at all. When I sign in from the authorization popup I'm left with a "Locate your calendar" dialog with nothing listed, it's just empty.
I don't have the Thunderbirthday-add-on installed.
When I import the preferences from a backup of the prefs.js-file into the current prefs.js-file the calendars are listed with the connection-problems but now the calendar-events aren't even shown any more. :-(
Can you please help me get my calendars back???
