Well, it looks like it is a cookie, which is easy to remove. Goto the preferences and look for where it talks about cookies, and then there should be a delete cookies button. Click on that and it will get rid of them. Warning, it will also get rid of any sites like this one that you have asked to remember you without having to log in again. If you don't want to reenter in all that info as you goto the sites again, then there should be a show cookies or manage cookies button that you can click and then you should see all the ones on the system. You can scroll through them all and find any that have a similar name and delete them by hand.
