I have the latest firefox 41.0.2 and I don’t have a home page assigned, so ordinarily I get a blank tab when I start FF on my win7 system.

The only difference I have on this system is that I use the OneTab add-on and have 13 regularly used URLs, etc. and that tab I leave, all others are closed before shutting down FF. I also have it set to open previously open tabs.

If I remember rightly CloudFlare represented 39% of deceptive domains, http://news.netcraft.com/archives/2015/10/12/certificate-authorities-issue-hundreds-of-deceptive-ssl-certificates-to-fraudsters.html. Probably why we are seeing lots of this in the V&W forums.
