There is no "Organize Bookmarks" item in my Bookmarks menu

I got a new hard drive and had to re-download Firefox. I'm trying to import my bookmarks from my old hard drive. I saved them as an .html file but am having trouble importing them. Whenever I try to import bookmarks, it only gives me the option to import from Internet Explorer, but my Internet Explorer bookmarks are old. I want to import bookmarks that I created in Firefox on my old hard drive. One of your help articles says I can import bookmarks from an .html file by choosing "Organize Bookmarks" from the Bookmarks menu. However, there's no "Organize Bookmarks" item in my Bookmarks menu. How do I access "Organize Bookmarks"?
