Firefox does not remember cookies for session (private mode)

[pedro22]

Firefox does not remember cookies for session (any version) private mode on the main page of Google.pl for information that use cookies, after clicking OK for a while it is fine but then again, the same information and the need to click OK - Chrome no problem I click once and is well.

Can someone check if it is the same - the point is: Google.pl



Only when this message appears it is well where you do not turn off the browser, but it occurs very rarely.

You know the purpose of "private mode"? Nothing is stored on your machine.
The cookie is only available until you close your session or the cookie times out.

Are you sure that the cookie does not time out?

I know what you mean "private mode" but at the time the session should be remembered - for Google.pl are 3 cookies and their time is:
Thu, 29 Oct 2015
Tue, 29 Mar 2015
Tue, 31 Dec 2015

so there are times out.
