This has worked well, including effectively en masse over the course my browsing, and has stored copies locally, under my control.

With Firefox 57 and web extensions, Scrapbook was effectively killed. Even the possible continuation under ScrapbookX or another fork, if that happens, appears as if it will have to write everything to browser-managed and constrained storage.

Now, I find my ability to conveniently and effectively maintain my own "record of events" becoming significantly constrained.

Aside from the technical side of my life, this makes it more difficult to keep track of all the political lies and backtracking I encounter, for the purpose of keeping straight what's happened and also potentially calling out such lies when I need to.

In a time where the Web seems to be more and more controlled by vested and reactionary interests, I find it all the more important that my user agent does what I want and need it to, including facilitating collecting and maintaining the records of interest and importance to me.

Security and protecting my private data are important to me. But so is not being dependent upon a Web that is increasingly fluid and manipulated, to maintain my access to its public record.

P.S. This also extends to my concern over the recently "baked-in" functionality for secured content management (DRM), and how this may be increasingly used in future to further lock up Web content.

What happens when our history is per forced maintained solely on commercial servers subject to commercial interests and manipulation?

I'm sorry if I sound like a pessimist, but in my experience, in general, "if they can, they will" -- sooner or later.

P.P.S. Yes, I can still "Save as...", or see whether the site "prints" as a usable PDF. And, in the short term, use a legacy version or fork of Firefox.

For the time being. But this is more cumbersome and time consuming than Scrapbook. And, per DRM and also what I feel to be a continuing trend, one step in a continuing trend towards user and public constraint.

I realize this is more aimed at DNAInfo style sites being shutdown, and based on the rest of the content has an agenda, but man, that's a big issue that's never mentioned.
