[SOLVED]Cookies disabled in allowed websites list

[Claudio Capobianchi]

I solved changing from http://example.com to https://example.com, since firefox 42+ manages domains differently (as I read on bugzilla trying to solve this problem).

Keeping "accept cookies from sites" box unchecked disables cookies even from websites included in the "allow/allow for session" page. Before updating Firefox this setting was working as regular.
OS Ubuntu Mate 14.04, affecting both 64bit desktop and 32bit laptop.
Here follows report made from desktop.
