Easy way -

Do not try with the chat window showing everyone online. It always freezes up.

Without clicking on any chat tabs below, Go to "My Account" ( )

Click Edit tab at the top, just below your name.

Scroll down, make sure you Un-check the box next to "Chat".

Then scroll down further, and click the "Save" button.

If you do this, chat should never show up again, until you re-edit your account on the "Edit" tab, select chat, and save again.
(unless we do something that resets defaults, which is generally unlikely)
