masquerading as Internet Explorer

Browsers identify themselves when they request web pages. Some web pages will only work if the browser states it is an Internet Explorer. To make your FireFox pretend it is an InterNet Explorer, surf to about:config and add a key/value pair

general.useragent.override = Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)

You can find out the information transmitted by your browser to the web server using netcAt:
