You can switch between IE and Firefox with one mouseclick in the Analyzing Browser (the screenshot shows the corresponding two menu items). Also you can switch between the main windows of IE and Firefox with a menu item of their toolbars.

Site Inspector makes website analysis easy. Here is a list of the most important features:

Main Features

  • Combines advanced website analytics with Internet Explorer and Firefox browsers
  • Includes stand alone browser application "Analyzing Browser" with Mozilla and IE browser engine built into one application
  • Analysis tools are available in toolbars and context menus inside the Analyzing Browser as well as in IE and Firefox

Cross-Browser Features

Site Inspector is a true "cross browser" application because it supports both the Internet Explorer and the Firefox/Mozilla browsers in three ways:

  • Site Inspector's stand alone browser application "Analyzing Browser" combines both browser rendering engines into one application
  • Site Inspector's comprehensive toolbars are available in all three browsers: IE, Firefox, and Analyzing Browser
  • Site Inspector adds various functions to the context menus of IE and Firefox

Using so called "element highlighting" all HTML elements of a webpage can be marked with a colored border, background, or text for an in depth overview of the web page's structure. This screenshot shows this feature: <table> tags are marked with a black border, <td> tags with a red doted border and <a> tags with a solid red border (please click the magnification glass to zoom in).

You can even hide (and show) all HTML elements of a specific type, e.g. you can hide all links or images.

Site Inspector displays various (usually invisible) parts of any web page

  • HTML source (syntax highlighted),

Element Highlighting

Using element highlighting all HTML elements of a webpage can be marked with a colored border, background, or text for a fast overview of the web page's structure.

For all links the linked URL and the HTML code of the <a> element can be shown right inside the webpage as well as the HTML code and the image URLs for all images


Site Inspector can overlay a pixel grid and customizable guide lines on top of a webpage, e.g. for pixel-by-pixel design checks.
