For about a year I’ve been accessing Google Calendar directly online.
This Sunbird add-on basically enables a read/write connection between Sunbird and Google Calendar.
When you download the add-on, it downloads as an xpi file.
From within Sunbird, go to Tools and Add-ons.
Once you set up the add-on, you’ll need to reboot Sunbird so that start using the features.
From your Google Calendar account, select configs -> Calendar configs.
press the orange XML button and then highlight and copy your unique URL.
Now that you have your unique Google Calendar URL, you’re ready to sync Sunbird.
The days of having to remember to export and import your calendar files are over.
You’ll see the following screen.
One flaw I notice with the plugin is that Google Calendar Task List items are not brought over.
