I use Thunderbird which now has the Lightning Calendar add-in installed. It's been there for awhile ... it happened automatically in one of the Thunderbird updates I guess. I finally decided to try it out today. The only calendar of interest to me is my personal Google Calendar.
The tutorial I found on setting up my Google Calendar in the Lightning add-on says I have to use the Provider for Google Calendar add-on and then specifies how to set up that add-on. It requires that XML address in order to link to the Google Calendar.
After spending a bunch of time trying to find a way to get the XML address I finally stumbled on a note that Google has discontinued XML links from their calendar as of sometime in November. Specifically, when I try to get a link from the appropriate settings page in my calendar there are buttons for ICal links and HTML links but no buttons for XML links.
Is there any other way to get the Provider for Google Calendar to link to my Google Calendar without the XML link? That is, can it use the iCal feed or the Google Calendar API? Or does it only know how to use the XML feed?
