From June 28th, 2019 to December 1st, 2021, 50% user give 5-star rating, 50% user give 1-star rating. for Anchor headings chrome extension.
Works exactly as advertised on pages where the headings have an id attribute! The other 1-star review probably doesn't know this fact, but an extension cannot add links to headings that don't already have a unique ID set by the website owner.
I really wanted this to work but it doesn't show anchors on any webpage.
