When I load Firefox it auto loads to the last page I was using. When this happens and I want another page from my favourites it inevitably tells me the page is not available - unable to load. I then go out of Firefox and then back into it whereupon the "missing" page appears. Questions is twofold (a) how can I stop this and/or (b) how do I reverse the election I made when stating with Firefox so that when I open I alweays go to my designated "home" page?
