Technical Support How can I unlink Facebook® from my account? How do I clear my cache? How do I enable cookies? How do I update my browser? I'm having troubles signing into an old account The website is saying that my email has already been used. What is JavaScript and why does it matter? Why am I unable to use the same email address on a different profile? Why can't I hear sounds for Messages & Alerts? Why does the website layout look different when I log in?
