I am just changing some tab settings in firefox and thought I would share the information to solve two of my previous annoyances:

1.  I know that the new IE allows multiple home page tabs, firefox 2 does also but it wasn't clear how to do this.  To do it you open the tabs you wish to use as home pages and then go into the tools, options and click the use current tabs!

2.  New tabs open blank! To fix this an extension is needed:  https://addons.mozilla.org/en-US/firefox/addon/1122

Why use firefox??  Firefox is open source and allows other developers to create tonnes of useful add-ons, I highly recommend it.
