     History: Use custom settings for history + uncheck all the checkboxes
3. restart
4. open a new tab (Tiles are displayed)
5. open Preferences -> Privacy and click "Show Cookies"

ACTUAL RESULTS
Cookies! WTF?!

I think we should prioritize this.

Comment 2

[Patrick Finch]

Agreed - I cannot reproduce here and this conflicts with documentation.

I see these exact same cookies BUT they seem to come from the welcome page. They're there before I even opened about:newtab once. Your STR is missing the step that clears those cookies after setting the prefs.

No matter how often I restart and open a new tab, I don't see any new cookies. We should resolve this as INVALID.

Even without turning on DNT, if I remove all cookies and open new tab pages, I don't see any cookies getting added.

If I remove all cookies on a new profile and reload the first run page: https://www.mozilla.org/en-US/firefox/33.1/firstrun/

I see the mozilla.org and optimizely cookies being set. Clearing cookies again and opening new tabs don't create cookies for me even without changing DNT settings.

Oh, yeah. Thanks for double-checking that. I guess we don't want cookies in general created by Tiles no matter what the user's preference.
