Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050302 Firefox/1.0.1 Fedora/1.0.1-1.3.2
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050302 Firefox/1.0.1 Fedora/1.0.1-1.3.2

The "Page Info" window does not show content that has been downloaded in
JavaScript and not displayed on the HTML page. For example when downloading URL
http://www.dilbert.com/ one can, by observing the status bar, see content being
downloaded from all kinds of hostnames that do not appear in the "Page Info" page.

Considering that this kind of downloads are almost exclusively used for tracking
users accross websites it would be a nice idea to see what kind of URL's were
accessed during a page download. One could then use that information when
blocking traffic in firewall, proxy or other program.

Reproducible: Always
