I surely wish that Firefox would display favicons on imported bookmarks -- Chrome will, Edge will, Opera will, and probably most others as well. Pain in the rump to visit hundreds of imported bookmarks in order to refresh favicons, and even this doesn't work for all of them - some mysteriously won't display while they display just fine in other browsers.
Just venting, not necessarily looking for a fix unless there's an add-in that will do this automatically for the latest version of FF.
