About this Add-on
You can select a Gmail account for every Thunderbird account. Signatures are synced on app startup, or when you click a button on the options page.
After installing, please visit add-on options page and configure your sync!
100% privacy friendly - nothing is sent outside your Thunderbird, and if you wish, you can configure your own OAuth credentials in Google. This is described on a wiki page. Starting version 2 it's just optional feature.
