I don't know how Firefox does it for Pocket, but you're overcomplicating it.
Just have to track what stays on your screen longer. They could also account for where your attention likely is on the visible screen based off what, if anything, you are interacting with (menus etc).
If you scroll past something in a second, but leave something else on your screen roughly in the middle without scrolling past it or moving to a menu for 3 seconds then it's pretty obvious which caught your attention.
