Since it is an Add-on, you should be able to enable or disable it in the Add-on dialog window. &nbsp;Just realized I have it installed in IE8 on my computer. &nbsp;You 'turn it on' on the Tools menu and turn it off by clicking on the 'x' in the upper left corner.<br />

Just see the IEHTTPHEADERS on the top of browser next to my url address box.

Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.
