My Friend used my pc while it was on, and cheked his Facebook account, now my pc remembers his log in information including his password. I'm trying to register with Facebook, but my pc remembers his info. I'm trying to delete this mistake. Can you help?

Question

A friend used my pc to check his Facebook account, and used my account. Now, my pc thinks I am he whenever I try to register with Facebook. I didn't catch the mistake until recently and have been trying to delete the info but cannot. I tried to access all of my security settings and even tried to erase the history but I don't seem to be getting anywhere. I believe he mistakenly commanded my pc to remember his username and password. I am not currently registered with Facebook, but would like to be but I am having this problem. Is it significant or not? I don't want his info crossing with mine because of my ips numbers or something like that. He also, without my knowledge, accessed his e-mail, too. His username seems to pop up even if I try to "Like" something on Facebook. This is when I noticed the problem. Then, when I tried to Register with Facebook, I was mistaken for him. The registration boxes come already filled in with his info. I do NOT want to invade his privacy. His entire profile comes up complete with friends, pictures, etc...Please help! I cannot make a 'save' disk since I don't know exactly when this happened and I've loaded new programs, including security and related files.

I am very happy to report that my server connection tech, which I called via landline, informed me to : 1. Open Tools 2. Scan down to Clear Recent History 3. Delete All. That was it! Unbelievable! Six hours of searching through the Windows catagories. I checked the results on an internet site, and viola! It was gone! Mozilla Firefox seems to remember the usernames and passwords irregardless of the option window that asks if you if want it to remember the user and password. I finally got in touch with my friend and he said he did not answer yes to the window, even though he was aware of it. No damage. I surely do appreciate everyones' concern in this, now what seems to be, a very simple solution. Cudos to Firefox! Thank-you! P.S. I now have to enter my information at the beginning of any password protected sites...no harm done! My friend is now condemned to the 'user account' site! lol...
