Like others, my Google calendar stopped working the last few weeks and couldn't find a complete fix. Searched around and found out there were changes made to Google's CalDav URL. This extension provides a fix by using your xml address for the URL. You can find it by logging into your Google calender. Go to Settings - Calendars - Choose your calendar and click on either of the orange xml buttons. Copy that URL and paste it into the URL field in your thunderbird calendar setup.
