Most of you probably know about this already, but I didn’t until today, so I thought I’d share 
Firebug Lite is just like the Firebug addon for Firefox, except it’s a piece of javascript. You can just open [URL=“javascript:var%20firebug=document.createElement(‘script’);firebug.setAttribute(‘src’,‘http://getfirebug.com/releases/lite/1.2/firebug-lite-compressed.js’);document.body.appendChild(firebug);(function(){if(window.firebug.version){firebug.init();}else{setTimeout(arguments.callee);}})();void(firebug);”]this link from any site to get Firebug going, regardless of the browser you’re using.
It’s incredibly helpful for debugging IE problems, because IE Developer Toolbar tends to suck.
