Firebug is one of the widely used Firefox plug-in for web development but using it in IE some time become difficult. Here is an easy way to use it in IE without referencing any code in your web-page.
Step #1 Add a favourite (I prefer to add to Favourite Bar so we can use it on a single click)
All of the above code should be pasted in URL of the favorite link and should be in one line
Above idea is fetch from “Firebug 1.5: Editing, Debugging, and Monitoring Web Pages”
