Hotmail registration date

Under tools > options > content > javascript > disable context menus (in firefox) you can set this to either block this kind of javascript or enable it.

In your case... you like this and so you enable it meaning: websites may use javascript to create their own context menu.

Try testing it by sending an email to the email address from another email address. If you get a response that the email doesn't exist, you're basically able to login to myspace b/c myspace doesn't really check after the account was created.

The account could have been deleted if it hasn't been used over 90 days.
