This article will describe how to add a signature in Mozilla Thunderbird that will be appended to all your outgoing messages. Note that University Communications provides a PSU standard signature that includes a PSU logo. Users desiring a simpler signature without HTML content may use this walkthrough to create one that meets their needs.
Also note that, while written for Windows users, the steps to attach a signature to your email in a Mac OS installation of Thunderbird are the same. The only difference will be steps 1-4; you will need to use the Mac OS equivalent of Notepad (usually TextEdit, which can be found in the Applications folder) to create the signature. Attaching it to your outgoing messages will use the same process as that described in steps 5-8.
- Mozilla Thunderbird must be installed and configured to retrieve your PSU Webmail for this process to be effective.
- Open the Notepad program. Click on the Start menu, then depending on your computer's configuration, navigate either to the 'All Programs' list or to the 'Programs' folder. Then, navigate to the 'Accessories' folder, and then click on 'Notepad.'

OR

- A blank Notepad window will open. Compose your signature as you want it to appear at the bottom of your outgoing email messages.

- Click on the 'File' menu, then choose 'Save.'

- A "Save As" window will appear. Navigate to where you want to save the signature file. Your 'My Documents' folder is a suggested location. If you want to use the same file across several computers, you can instead save it to your H: drive. Once you have navigated to the desired location, name the file 'signature.txt' and click 'Save.' Then close Notepad.

- Set Thunderbird to use your signature. Open Thunderbird, then click on the 'Tools' menu and select 'Account Settings.'

- In the window that appears, check the 'Attach this signature:' box, then click the 'Choose...' button.

- A 'Choose a File' window will appear. Navigate to where you saved your signature, then select the file and click 'Open.' Click 'OK' to close the Account Settings window. Now your signature will automatically be added to the bottom of every message you compose.

- Your new signature should now be visible at the bottom of all your newly composed messages.
- If you have followed the above steps and you still cannot see the signature you added, try closing Thunderbird and starting the process again.
If you use more than one computer on a regular basis, it is advisable to save your signature in a location you can access from any computer, such as your H: drive. Note that you will have to follow the above setup procedure for each separate installation of Thunderbird in order to have the same signature appended to all your email messages. Setting a signature within Webmail will not affect the signature you create in Thunderbird.
