Icons replaced with blank square outlines
Has anyone seen this? While using Safari, where there should be indicative icons, there are frequently square box outlines (like a checkbox in a Pages document). Notice the bottom row of the first attached pic. There's no way of knowing what will happen when you click on any of those squares. It should look like the second picture (from Firefox browser). Notice the editing tools icons. Can anyone help?
