I look at porn on my Android phone. I use Private Browsing to do so. Why are my Private Browsing addresses appearing as Firefox Suggest results that appear outside of Private Browsing as well? And why does Pornhub show me a personalized home page when I'm using Private Browsing? None of these pages are in my browser history because I've only accessed them via Private Browsing. But these "features" sort of defeat the purpose of it don't you think?

I've just switched from Chrome to Firefox and never had this issue with Chrome.
