1: Is that relevant?
Hard to say. I try the sites people complain about seeing the redirects on with my iPhone with any ad blockers turned off, and there they are. And yet, I'll go to the same site on my Mac (High Sierra, also in Safari with my ad blocker off), and nothing. No ads. At least, not the redirects that are currently plaguing iOS.
ArtStoneNC is quite correct that iOS in particular matters with browsers. Since they are all required to use iOS's underlying WebKit, it really means they're all the same base browser with their own interface.
2: Lastly, do you store passwords on the sites you visit, and credit cards, on your phone?
No. But that's mostly because I use my iPad and iPhone for reference browsing more than anything else. For any actual commerce, I use my Mac. I use my iPhone 6s for the web as little as possible simply because so little of a site fits on the screen. It's just a pain to use most of the time. The iPad at least has a decent amount of working space.
I saw this after I posted my last reply. By the way, I can’t hit “helpful” to any responses. Sorry if that helps your credibility in some way. (You too Kurt)
Points are the goal of some users. It truly doesn't matter to me, and never has. There was no point system of any kind when I joined. I spent the first six months I was a member just reading, reading, reading. I had the first Mac I ever bought new (a G4 tower) and wanted to learn a lot more about the ins and outs of the Mac and its OS than just using them (as I did at work). Then it kind of became habit to stay in order to constantly learn and help others where I think I can.
You can still click Helpful on any post you feel deserves a mark. Only the person who started a topic can mark Solved on anything, and two Helpful's that will give those two posts an immediate gold star and 5 points. But, any post that receives 5 or more Helpful clicks from any users who want to click on the button also gets a star and 5 points. So, you'd still be helping ArtStoneNC on his way to a Helpful star for that post.
