Multiple Homepage in Mozila?

You mean firefox..?? It already has that feature.. Just open all the pages you would like to have as homepages in multiple tabs and the go to
tools >>> options >>> main >>> Under home page click the use current pages tab and then in the field when firefox starts select open my homepage

Now every time you start FF, all your homepages open in individual tabs..

open all the websites that u want to add as ur homepages and then tools>Options>main>use current Pages...and voila the next time you open firefox all the pages open

thanx , i was not knowing this .
