Why does my laptop sign me out of every website whenever I close it?

[FAiLED]

It didn't use to be like this, but recently, every time I close my laptop, I get signed out of every website. Deviantart, facebook, messengers, subeta.net. On all of these websites, I check the little box saying "remember me" or whatever. Every time. It's really annoying that I have to sign into everything. How can I change this?
