Custom Internet Explorer Script or plugin to remove specific Javascript code

I need to be able to have a script, plug in or something that would automatically remove all "display: none;" from any of the Javascript on the page. It is for auditing and testing. It must be able to work on all versions of IE at least on 6 and current version 11 A typical page could have the following: <input class="inButton" id="ButtonPri" style="width: 70px; display: none;" onmouseover="this.className='inButtonHover'" onmouseout="this.className='inButton'" onclick="stampa();" type="Button" value="Print"> and I would want it to remove the display: none; so it would look like this <input class="inButton" id="ButtonPri" style="width: 70px; display: none;" onmouseover="this.className='inButtonHover'" onmouseout="this.className='inButton'" onclick="stampa();" type="Button" value="Print"> and to be done automatically as long as the plugin or script it active. I need to be able to turn it off and on. I can use the developer tools DOM explorer, however it takes much too long and I have to audit about 1000 pages or more.
