"Organize Bookmarks" does not appear under Bookmarks menu, even though Help advises to go there.

I've needed to eliminate Bookmarks. Because I have no "Organize Bookmarks" or "Manage Bookmarks" option under the Bookmarks menu, I've tried dragging bookmarks off the list onto my desktop. I've tried right-clicking to get a "delete" option (but there is none). I've gone to "Help" where I'm advised to click on the Bookmarks menu item, select "Organize Bookmarks," and proceed from there. An image of the items in "Organize Bookmarks" appears in this "Help" instruction. BUT -- "Organize Bookmarks" does not appear when I click the Bookmarks menu item.
