IE Sucks - A Free and Open-Source Tool
IE Sucks is a free and open-source tool that lets you see HTML page elements that help Internet Explorer to load faster, such as meta name="generator" content="[name]">, meta charset="utf-8">, meta http-equiv="X-UA-Compatible" content="IE=edge">, and so on. The color of these elements changes according to the URL that they point to, so it's possible to know what kind of information is on a specific page. In addition, the plugin can highlight specific HTML attributes, so you can easily find specific values for a given element.
The main goal of this tool is to show how Internet Explorer is holding back progress by supporting poorly designed HTML code. It does not support all Internet Explorer versions, so you will need to check the supported versions for your browser.
