Signature sync add-on

Signature sync for Gmail, a Thunderbird add-on

View project on GitHub

This extension allows you to easily update signature of selected accounts in Thunderbird with the signature from your Gmail accounts. Syncronization works in one way, your local signatures are overridden by Gmail ones.

In order to sync a signature, go to the settings page, enable an account and connect it with Gmail. Signatures are downloaded on every startup or when you click in settings.

Beta! This is still a beta version. It can work unstable.
