About Firefox. Can it be?

6. I looked up the problem. It was happening on every web page.

I had to use reader mode extension of Firefix, or use safari to copy text. And reader extension for Firefox does not toggle back. Even turning it off and refreshing the page!

I save pages to pdf for reference. Safari does a good job with "Reader" selected. But I can't set "pdf" as a default printer, so I have to select pdf every time.

Firefox has a great print style sheet, and often, "simplified" mode is even better.

Just search on "firefox won't copy text" without the quotes, and screens full of responses come up. I will turn off auto-updates so it won't revert to bad behavior.

Copying has been a Firefox problem, not just unfriendly web pages.

As for your point, on a well-behaved browser, nasty sites can be tamed by using a "reader" extension or by turning off javascript for the site. On ios, there is an app called Sheriff that lets you kill javascript and/or cookies selectively for each site. I use it.
