can i insert 'mozilla firefox start page' onto my toolbar instead of the standard google on the search box

I'm having problems like a lot of others with Google as it has removed it's 'UK only' button from it's home/search screen. I prefer the Google Mozilla Firefox Start Page as it gives me the options I need. On the Firefox toolbar search box, which drops down to give search engine options, can I link the Mozilla Firefox Start Page to this box? Thankyou.
