Hai friends,
Anyone know firebug like plugin for IE.Pls help me

Internet Explorer isn't really designed for plugins although very few are available. I would suggest using a browser like Firefox, Opera or Crome as they all have that feature.

In IE8 there are the IE Developer Tools which, while not as good at inspecting elements and CSS, has a very powerful built-in Javascript debugger. Note that Firebug console.* calls are, for the most part, compatible with the IE Developer Tools.

<disclaimer>This being said, use Firebug</disclaimer>
