This addon gives you the ability to add markers inside a webpage which will help you in navigating back and forth conveniently on the page.
You have to press Ctrl+Click to add markers.
You don't have to worry about messing the order, this addon takes care of preserving the order with the webpage.
You can also delete the markers if you like.

Enable this addon by clicking on the icon after installing, you'll see a new marker UI appears.
You can also remove the UI simply by clicking the marker again.

I created this addon as I needed something like this.
