Thunderbird 78.5.0 & Provider for Google Calendar 78.01 Win 7 x64

When I go to the Tbird calendar page, after the machine has been sitting for a while (overnight), all the entries are blank, including holidays.

When I click the hide button over to the left of the calendar, and then click again to show, the entries re-appear. This is for my google calendar and the U.S. Holidays.


      • I'll give up Windows 7 when they pry it from my cold, dead hard drive.

Try removing the Provider add-on, restarting TB, and installing the add-on again. Or, avoid add-ons and use CalDAV directly: https://support.mozilla.org/en-US/questions/1304356#answer-1368791
