What I'm looking for is a a bookmarklet, extension or web app that allows you to save your location when reading long articles, tutorials, e-books and other long web content.

It can be a bookmarklet (that saves in a cookie), an extension or a web app (e.g. I wish Pocket had this feature).
However, I've searched for a few hours, and all I could find is this:
