This is a perfect tweak for those of us who love to put our own original stamp on things. In this case, it's our Internet Explorer or Firefox browser title. Allow me to clarify: when you open up your browser window, the upper left corner displays the current page, followed by "Microsoft Internet Explorer" or "Mozilla Firefox". Follow my directions to make it say whatever you like. I've tested this tweak successfully on XP and Win98 systems.
Steps for IE
<warning> Before you mess with the registry, please back it up so that if you make a mistake, you don't get screwed. </warning>
1. Open up Regedit (Start>Run>Regedit).
2. Navigate to this string: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main
3. Create a new string value (Right-click "Main" key folder, select New>String Value).
4. Rename the value "Window Title" without the quotes (Right-click value, choose Rename).
5. Right-click "Window Title" and choose Modify. In the value data section, type your title of choice. Mine says "Elect Sarah in 2004!"
6. Now, launch a new instance of IE and marvel at your clever changes!
Steps for Firefox 0.9 and up
Wouldn't you know it... there aren't really any complicated steps to do this. Just download an extension called Titlebar Tweaks and you'll be good to go.
