IE user here.
Why?
Because I know it. No one knows what Edge is doing.
Getting tough though, and I resent that.
Someone needs to come up with a user-friendly, user-protecting browser.
I've seen a lot of positive comments here on FR about the "Brave" browser, with regard to privacy and ease of use:

It runs on Windows, MacOS, Linux, and the mobiles iOS and Android.
I haven't done much with it myself, other than download and try it on my Mac (I'm currently wedded to Firefox for historical reasons). It looked pretty good.
