Importing Mozilla Firefox bookmarks into Safari on your Mac is really easy. Firefox stores its bookmarks in an HTML file that can be parsed by Safari. In Safari, simply click on the File menu and select Import Bookmarks. This will open a file selection dialog box. Firefox stores its bookmarks file in your profile directory. Simply navigate to the following directory inside your home directory: ~/Library/Application Support/Firefox/Profiles/[random_characters]/, and select the bookmarks.html file.
