Rated 5 out of 5 stars

But, like Geek Girl, I'm having problems today. I think an update must have broken it. Thunderbird calendar won't show my calendar entries that are based on my email address. I get a message on my phone that I need to authorize access, which I do. But even though the message goes away, the calendar is still broken and won't synchronize with the calendar that shows up perfectly well on my phone. I suspect there has been a coding error.
