My apologies. I had fully intended to remove that sentence. You were completely correct about iOS only allowing WebKit to be used as the basis for all browsers. Also about the .top gTLD being hosted in China. Both of which I agreed with.
I have had Adblock installed since Apple added 3rd party content filters. But because many sites overtly block their content, it is almost always turned off.
That doesn't make sense to me. "Many sites" overtly block whose content? They sure wouldn't block their own.
More problematic is web sites don't work if Adblock is active without any warning.
What do you mean "don't work"? I have yet to visit any site that doesn't work. It's not unusual for a site to complain that you have an ad blocker running, and pretty please turn it off. But that's not the same as "doesn't work". They're just trying to force their control on your computer. No way. You can almost always find the same content some where else. Or, simply click the AdGuard icon at the top of the browser to disable it for the moment so the site will load. Often, you can enter the site with it off, then immediately turn it back on. The site is initially happy it didn't see an ad blocker, but then doesn't pay attention to the fact you've turned it back on.
I have already proposed that Safari have the same solution that is implemented in Chrome, which is to not allow javascript to disable the Back action.
Apple has already done that. If you get stuck in one of the idiotic, "Your computer is infected with xxx viruses!!! Call this scam number now!!!" sites, you can click the back button to get out. A box will pop up asking if you really want to leave the page. These JavaScript loops can no longer lock you into the site. As with the way Apple normally does things with Safari, you do need to be running an up-to-date version of Safari. Which means you must be (at this point) running at least El Capitan.
"Just use Chrome" is another perfectly valid solution.
No way in any universe will I use Chrome, or any other app from Google. Unless, that is, you don't mind Google collecting marketing data on your computer and web usage the entire time your computer is on. It does this whether Chrome, Google Earth or its other apps are running or not.
There's nothing stopping you from setting Chrome, Firefox or other third party browser as the default. Well, not in macOS. It is a nuisance you can't do that in iOS, and doesn't make sense why such a simple, optional choice hasn't been added.
