    If you have tried our Written Instructions for installing your signature into Thunderbird for Mac and you run into any issues, please read through this troubleshooting guide before contacting Support for further help.


    My email signature doesn't look right when I compose an email

    When composing an email within Mozilla Thunderbird for Mac you will see the table and cells of your email signature outlined, this is completely normal. When you send your email, it will display correctly to your recipient.


    I am composing an email and I can't click on any links or social media icons

    In compose mode, most email programs won't allow you to use the links in your email signature. Check to see if your email signature has been installed correctly by sending a test email to yourself instead. The links and social media icons should work when you receive the email.
