Not as well as it used to!
Specifically, in the browsers of the 1990s you could "scroll while dragging": i.e., if you start dragging to select some text and you reach the bottom of the window, the window would scroll, allowing you to select more text than just what was on the screen when you started dragging. But at least in Firefox, that does not work anymore. (More precisely, you cannot scroll down although if you start dragging at the end of the selection, you can scroll up.) In other words, browsers have gotten so complicated that even an organization like Mozilla that spends millions of dollars a year on browser development cannot preserve all of the conveniences users used to enjoy for handling text.
My main response, though, is that the browser organizations (Mozilla, Google, MS and Apple) could have balanced the interests of content producers and content consumers instead of their giving content producers (and web-app developers, and marketers) almost everything they want like they have done. It's not as if the New York Times would have withdrawn from the web if the things they could do with code and with stylesheets were more limited.
