Hopefully blog.mozilla assure it's for your own good: trust You know.
I switched to qupzilla recently. It's sort of a faster opera old v12. More to my liking than palemoon or waterfox, just for the ability to have a real customizable speeddial
Still use firefox. Opted out of the whatever page, not that I ever close my tabs/windows anyway. Use addons to take care of the rest of my basic privacy needs. Don't see much of a problem. Only things that get through are what I want to.
