And if you don't like it, you can reconfigure said browser to block them.

Oh?

I'd love it if that were true. But increasingly, it's not.

Take the YouTube app on iOS. It has no extension functionality. And it's de facto the YouTube browser.

Is it a web browser? Depends how you look at it. YouTube is the web of videos.

Even if we're talking about the actual web, Chrome on iOS doesn't seem to be configurable with extensions. Certainly not easily reconfigurable. In fact, Apple blocks apps that become too configurable, like Expo's old "Scan a QR code and now see your app running immediately" functionality.

Sadly we no longer seem to live in the world where you're encouraged to reconfigure anything.
