Can't hide Facebook chat sidebar?

[anon]

Does anybody know how to hide the Facebook chat sidebar?

It's changed again and next to the gear icon, there is only option to "Create new message".

When I click the gear box, there is only option to enable Chat Sounds, Advanced Settings, Close all chat tabs and turn on chat.

My entire Facebook layout is messed up and I can't see my search bar unless I hover over the chat panel on the right hand side.

Settings may differ from one browser to the other.
