Every time I switch from Gnome to i3, some sites cookies and localstorage got lost, including google.com, and Chrome got 'Sync paused'. I have to re-login to most sites I often visit, like stackoverflow, github, google, live.com, etc.
But not all, some sites still auto login, like this blog and pan.baidu.com.
And actullay not always, sometimes a reboot is needed to reproduce this issue. I don't know.
I have no clue, it's confusing.
Firefox doesn't have this issue.
