I previously would hunt through the source code for anchors to share a particular part of the page with someone else. This addon makes it so much easier by showing the anchors right alongside the content. Thanks so much for developing this!
Push the add-on's button, any anchors coded into a page's HTML are displayed immediately, directly adjacent to their content. Right-click on an anchor and copy location to clipboard, the page URL + anchor is copied. Press the add-on's button again, the anchors are hidden. Dead simple and so straightforward. This is exactly what I needed.
