I have set the "when firefox starts" and "home page" values, but when I reboot the computer (or more accurately, when I restart the computer as it has been crashing frequently of late), those values get reset to some default value which I don't want. If I close Firefox then reopen, the correct values appear. How I do store the values over reboots? The values are when firefox starts: show a blank page home page: about:blank I'm still using Windows XP so there's no problem about directory permissions.
