This is an old trick and thought of sharing. Do you ever need to open multiple pages each time you start your browser? I do. I need twitter+facebook+ some project pages+ engadget :D If its yes for you then this should help.
Opening multiple pages on Firefox
Open Firefox --> General --> Homepage Box --> Enter multiple URLs with PIPEs within. Thats it ;)http://facebook.com/|http://classictutorials.com|http://twitter.com/|http://localhost:8081
