Think of it as stocking a library. You're not supposed to read an entire library. I use Firefox and the "PlainOldFavorites" add-on. This means each bookmark is created as an individual .url file in the Favorites folder. Once a week or so I go through it and delete or move each .url file to the most appropriate folder in my personal library of topics. i.e. If I bookmark something about a new kind of map projection it…
Don't do it (as it saves a lot of files - js, css, images, besides some of those could have malicious code...). Just pdf-print it in Chromium and bookmark that pdf in FF with the same tags.
