Firebug is what makes Firefox great, but how about other dysfunctional browsers like Internet Explorer? There is a way to use a stripped-down version of Firebug on IE, thanks to Firebug Lite.
To use it, just drag the bookmarklet icon below to the Internet Explorer Favorites bar.
NOTE: It might take some time to load the bookmarklet, i.e. ten, twenty seconds or even more.
