How to hide this Popup?

[Jafix]

When i open an shred XD link, the sidebar AND this popup always apears. 
Doesn't matter how i left it? 

Would expect, that it is remembered in my account when i "OK"ed the popup and maybe the state how i "configured" my view (sidebar hidden/shown).

I'm not getting the popup, but the sidebar seems to always be there. I wouldn't count on any update in that regard though. You can check if your browser is blocking cookies which is usually how the "viewed" status of tooltips is remembered.
