Automatic Sign-out

I have to sign in every time I open the site. I don’t know why every time I close the tab it signs out my account. It is very time consuming to sign-in every time.
Anyone plz help!!

Security is time consuming.

I had this very same problem. I formatted my PC and it was doing well, i don’t know why that happened, but it did and i didn’t know what to do like you, i mean even now i don’t know what happened.
