How do I mask the Firefox browser signature?

Does anyone know of a way to mask the Firefox browser signature, so that it looks like Internet Explorer to the rest of the world? I know there is a plugin to use the IE rendering engine, but that kind of defeats the purpose of using Firefox. What I'd really like to find is something that will simply replace the Firefox browser signature with something else and not affect how the browser itself renders pages, etc. Is there anything like that out there?

Try this User-Agent switcher plugin for Firefox: User Agent Switcher 0.7.2
