Element Removal Chime

Receive an audible alert when an element of a page is removed, or when the window unloads. After installing the extension, the context menu (right-click menu) in web pages will include an “Element Removal Alert” option. Right-click on an element you want to watch and select "Element Removal Alert" from the context menu. This opens a menu showing the element you clicked, and some of its ancestors in the DOM tree. Click the element you want to watch, and a watcher will be added. A red outline and the word "Watching" will be shown over the watched element to confirm what you've selected. Whenever the watched element is removed from the DOM, or whenever the window unloads, a chime sound will be played.
