Debugbar - firebug for IE, IETester, Companion.JS - Javascript debugger for IE

Lots of web developers love Firebug in FF, but it's hard to debug anything in IE or No proper debugger tool is there for IE. Today I came across a debugger tool for IE - Debugbar

It's an Internet Explorer plug-in that brings you new powerful features.
- DOM Inspector: View DOM Tree and modify tags attributes and css attributes on the fly to test your page
- HTTP Inspector: View HTTP/S request to check cookies, GET and POST parameters, view server info
- Javascript Inspector and Javascript Console: View javascript functions for easier debugging, see Javascript and AJAX code
- HTML Validator: Validate HTML code to correct and optimize your code and html size of your page
- And many more features: See page cookies, get pixel color on a page, make a page screenshot...

In DebugBar 5.0.2 BETA you will find...
- Greatly improved DOM tab : for each element, get the applied styles, computed style, layout and attributes


- Fully unicode, support for international characters
