Here's a neat Firefox trick-- if you would like more than one "home" page to show up when you click the home icon-- each page will appear in its own tab-- just type the URL of each page into the usual home page field (Tools -> Options -> General) separated by the "pipe" character (it appears on my keyboard as the shift-backslash key, and looks like this: | ).
For example, to open the BenefitsLink search page and the BenefitsLink buzz page as your two home pages (each on a separate tab), you'd type this into the home page field (ignore the word CODE):
CODE
http://benefitslink.com/search|http://benefitslink.com/buzz/short.html
