Logged out of and back into what? Your mobile app? Your web browser tab that is left open indefinitely? I no longer use FB, so just curious. I know people that never log out of FB, and have closed their browser window/tab thinking that was good enough even though the "remember me" type option was checked. Opening a new window/tab to FB would show their account just like nothing happened because they did not log out. I know this is to FB's advantage of tracking all the things, but wow what a security nightmare.

There's no remember me option antymore, it always remembers. You have to log out manually and/or set your browser to delete the cookies and/or use Ghostery if you don't want FB tracking you all over the web...
