Will you adding the menu item to undo kittening, like the Chrome version? That would make it five stars.

Edit: until then, extension users can get the unMAKA functionality by making a bookmark with the following URL:
javascript:(function () { for (var i of document.getElementsByTagName("img")) { if (i.hasAttribute("makareplaced")) { i.setAttribute("src", i.getAttribute("makareplaced")); } } })()
