Suspicious failure of Thunderbird connection to Google calendar
Two days ago I got a suspicious message in the form of a window that opened on my Firefox browser, purportedly from the author of Google Calendar Provider, soliciting contributions. Not expecting the window, and not certain of its authenticity I closed it.
Yesterday my calendar failed by popping up two notifications from my Google calendar via Thunderbird. I could not dismiss them. Other users have occasionally noted this issue. I tried closing and opening Thunderbird and rebooting. The alerts persisted.
So I removed the Google calendar from Thunderbird. The alerts went away. Hooray!
But when I reinstalled my Google calendar through Calendar Provider, the calendar showed up on the list of calendars, but non of its events appeared. Synchronization, closing Thunderbird, and rebooting did not help.
I can't tell whether I was hit by some kind of e-blackmail (pay up or else), or if something changed in Thunderbird, or what. No antivirus measures have been triggered, and my Windows 11 system is set up as a local account without administrative privileged. I am up to date on Windows updates. Running Thunderbird 128.8.1 esr
