Text Complete

If you're looking for a way to increase productivity while using web forms, the Text Complete extension might be just the thing you need. This extension adds useful shortcuts and auto complete functionality to various text fields found in Firefox and Thunderbird message composer.
What's great about this extension is that it allows you to define shortcuts based on your personal preference through the extension options. Additionally, you can share these shortcuts with others by storing them in a central xml file on a web server or network share.
Originally created to help support staff enter responses more quickly into web-based support systems, Text Complete is useful for any information that is repeatedly entered into form fields. Whether it's email addresses, phone numbers or just adding a signature to the end of a forum post, Text Complete is here to make your typing process more efficient.
All you need to use this extension is a Firefox browser version 1.5 or later. So if you find yourself typing the same information repeatedly or simply want to speed up your typing process, give Text Complete a try.
