Outlook and Thunderbird have options to insert signature in your emails. The webmail also has similar features but they are not very user-friendly and don't allow you to add complex signatures that include your web address, social networking and instant messaging information to share with your clients, friends and families.

But thanks to user-friendly tools like WiseStamp and others we can add signature that contain a wide variety of our information.


How to add signature in Firefox?

WiseStamp is a Firefox add-on works only with Firefox browser but is compatible with Gmail, Yahoo, Hotmail and AOL Webmail programs.

With WiseStamp we can add images, HTML (bold, italics, colors and other styles). It also adds a wide variety of social networks (such as Twitter, Facebook, MySpace, Linked-In, Delicious and others) and instant messenger clients (Yahoo, Google Talk, MSN and other chat clients). If you are members of them and want to share with others, then you can add your user details and WiseStamp adds the information to your signature.

1. Install the WiseStamp add-on here.
2. After installing this Firefox extension, restart the browser.
3. You will see a "WiseStamp Icon" a rubber stamp-like picture. Click the icon and click "Edit Signature".
4. Enter the pertinent details as shown below, your blog information, Twitter user name, web address, contact information etc.
5. Save the Signature.

After you begin composing the email in Gmail, Yahoo Mail or others it will either automatically enter the signature or you can manually click the stamp to enter the signature. You can create separate signatures for "Personal" and "Business" use. You can modify the options by clicking the WiseStamp icon --> Edit Signature --> Click the Settings tab to make the changes.
