"The show more bookmarks" double arrows are missing on the right side of my Safari screen. I have gone to settings and under Safari have turned on the "show bookmarks bar." The bookmarks bar is there but the double arrows for the "show more bookmarks" bar are missing. The same is true for my MacBook Pro. I bought my MacBook Pro two months ago and I have updated everything. My iPad 3 is one month old. Can anyone help me?
