I'm completely lost here... some help please!!!
I've downloaded this add-on so I could add my Google Calendar to Thunderbird. Well, what's the next step? What now????
I don't get my Google calendars within Lighting. I don't even the option to do so. Where is it??

This review is for a previous version of the add-on (0.7). 

File > New > Calendar, Network > Google Calendar > Enter any of the xml or ical url's from your Google Calendar Web UI (Settings > Next > Next > Finish
