Site Inspector - User Manual
The context menu does not show Site Inspector entries
There are webpage elements (such as Macromedia Flash movies and Java Applets) that have their own context-sensitive menus—when you click on them with your secondary (right) mouse button, a different menu appears than when you click on another part of the webpage. To access Site Inspector functionality in this case, simply click on another part of the webpage or use the Site Inspector toolbar buttons.
What is Site Inspector?
Site Inspector is a powerful HTTP-client/server test application designed to pinpoint critical performance issues in your web site or web server that may prevent optimal experience for your site's visitors.
