Two weeks ago I wrote that my bookmarks list had expanded to cover almost the whole screen; this was my mistake. I meant to say that it is the list of my '''folders''' under the FF Bookmarks menu which is now displayed on a much wider screen than they were originally. When opening a folder, the list of bookmarks is correspondingly wide. I have tried shortening the titles of bookmarks, to no avail. My folder tiles are only one word in length. Navigation of this much wider folders list is also erratic and not smooth, as it was before this change occurred. Thanks for your help.
