Choose On my computer and click Next Continue.

All the data is stored inside an internal database (the file local.sqlite in your Thunderbird profile). When choosing 'On my computer', you can only use the calendar on the computer you're working at. Now you need to choose whether you want to create the calendar 'on your computer' or 'on the network'.

Alternatively, you can use ≡ > New > Calendar…, or File > New > Calendar….

Choose New Calendar… from the context menu.

In the calendar list on the left side of the screen.

Right-click Hold down the control key while you click.

Unfortunately, Google does not support tasks through CalDAV. You can choose which calendars Google will expose in your Google Calendar Sync Settings. This will be fixed after the upcoming rewrite.Note: If one of your Google calendars is not found or not accessible, it might not be set up for syncing. Particularly, adding a contact to (or removing it from) a Thunderbird mailing-list doesn't currently reflect back to Google. 6) Please keep in mind that some limitations apply, see 'Current status and roadmap / Known limitations'.

5) You are particularly suggested to enable the 'Read-only mode'. (And if this seems complicated, please blame Google, not me, as I'm forbidden from providing already built-in credentials.) 4) Also, you might have a look to the various 'Account options' and their meaning. Please refer to 'How to generate your own Google API Console project credentials' for a step-by-step guide on how to generate them. 3) You also need some specific credentials by Google to use this add-on. After that, just open the TbSync management interface and add a 'Google' account.

1) BACKUP YOUR (THUNDERBIRD AND GOOGLE) ADDRESSBOOKS BEFORE RUNNING THIS SOFTWARE! 2) You must install and enable TbSync first, because this is an add-on to it.
