I often come across a long article that I want to read, but can’t read it immediately. That’s when the Firefox extension ReadItLater comes in handy. It puts a checkmark in the right side of the address bar, which can be selected for any page to save to the list. Although a bookmark folder would be able to serve the same purpose up to this point, the convenience comes from two things. The first is the button that is added to the toolbar, which allows you to access a drop down menu which has all the pages you have saved. The second is the Paperdroid Andriod application, which saves copies of the pages you have marked locally, so that you can read them anytime.
If you often have articles you want to read later and don’t mind risking extension bloat, ReadItLater is worth a try.
