How do I add a signature to my emails in Thunderbird?
The instructions are the same for Thunderbird on every OS. (As of Thunderbird v22.214.171.124)
You can create a signature file in Wordpad or Word and save this as a text or html file to your desktop or other folder.
(Do not save it as a Word document, TB does not recognize the format!)
Then open Thunderbird,
- Go to Tools > Account settings.
- Click on the Choose button in the Attach this signature section and browse to the desktop or other folder where you saved the signature file.
- Choose this file and click OK to close the Tools window.
Now this signature will be added to your outgoing emails.
