blocked out of hotmail access, how can I reset to access e-mail

The last time I was able to access my Hotmail I was sending a e-mail and noticed in my (TO) for address that an entry was on my contact list called Kinky chat in bold letters without an address. This may be spam? I could not delete the entry although the computer did not indicate any suspicious activity after running program checks. I tried to block this Kinky chat site. Once I logged out and tried to regain access I have not been able to get into the e-mail. I can access the Hotmail from another browser, however, the Kinky chat entry is still on this site. How can I gain access to Firefox for my e-mail. I truly enjoy Mozilla.
