How do I set permanent private browsing in Yosemite?

[iMore Question]

I prefer private browsing all the time. In the previous version of the operating system, I could set private browsing and it would apply to all my browsing.

Now I have to open a private browsing window, and when I close that window private browsing closes. Is there a way in Yosemite, to set it and forget it? i.e. set it once and it applies until I make the decision to close it.

Set the private browsing window as your homepage. It should open up every time.
