There used to be this neat little extension called Read It Later that let you do just that. Bookmark and save it so you could read it when you were offline or the page disappeared. Later they changed their name and much later Mozilla bought it and added it to Firefox without a way to opt out. It was renamed to Pocket.

Pocket is not integrated with your bookmarks. For offline consultation, you need a separate app. Of course this app is not available on Linux, where you have to get some community provided tools.

Bookmark integration would mean one software, with the same UI, on every platform, and only one listing for your whole archive system.
