I intend to remove the prefixed CSS property -moz-force-broken-image-icon in bug 1348208 [1], and add a new "browser.display.force_show_broken_image_placeholder" pref to replace it.
This property is for forcing showing the image placeholder for broken images. It is initially added for making Gecko's behavior align with IE. However, as far as I can see, no other modern browser has such behavior (at least by default) nowadays. None of Chrome, Safari, and Edge shows the placeholder icon for broken images. Since this only applies to broken images, I don't expect it to break webcompat. There are some non-trivial number of mentions to this property according to search result, but it seems to me most usecases are that authors want to find broken images easier, and thus most of its usages seem to be in user style rather than author style. It is a clear indication that it should be a pref rather than a CSS property. BTW, I guess devtools may want to add some support around the new pref to help authors find broken images.
