Through a bookmarks “mishap”, the Bookmarks Menu folder was deleted. Last time this happened a couple years ago, I was able to recover my bookmarks and folders via iCloud Settings - Advanced - choose which date. Now, you can only recover individual bookmarks for a limited time.
The screenshot was made while in the alternate user on my MacBook, running Mojave.
Just adding a folder called bookmarks menu does not yield the icon you see in the screen cap, and I would guess some other functionality.
I suspect it involves a file in the User - Library - Safari folder.
Anyone have a solution for this?
