cannot really pin the most visited tiles on the new tab
I try to pin the most visited tiles on the new tab. It works temporarily. But wenn I restart the computer and open firefox again, those once pinned tiles turn out become 'unpinned'. The settings are just not really saved. This problem bother me somehow. I am thankful someone can help me to fix it. My system is win7 (32bit), firefox 45.0.1 (32bit).

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
