Multiple home pages in Firefox

Don't know if this is a new feature in the Firefox 3 nightlies or if it's just some obscure feature in Firefox that I never knew about, but apparently you can have multiple home pages open up when you hit the home icon or when your browser starts up.

Tools/Options/Main - type in or copy/paste the URLs you want to open up separated with a pipe (|). Or open up the pages you want to set as home pages in separate tabs and click the 'Use current pages' button.

It's pretty neat.
