First issue: The default username used to be admin/blank. With the newer firmwares it is now admin/admin.
You shouldn't have issues with FF logging in. Check that FF does not have some bogus password remembered for that IP address. Also make sure you are typing "admin" for the username.
Honestly though, the draytek has always been best configured using internet explorer. I would highly recommend you always configure it from IE, firefox sometimes pre-fills fields in for no apparant reason and you end up with a config problem. IE is also more stable browser to use when upgrading firmware on it.
In system maintenance > management, there are options re allowing management from the internet - this may be the cause of problem #2.
