By "favorites", do you mean the bookmarks menu, or do you mean the "top sites" on the new tab page? If you're referring to the old bookmarks menu (the one that looks like this: https://cdn.ghacks.net/wp-content/uploads/2013/11/bookmarks.jpg ), you can add that back to firefox. Cick on the hamburger menu (the icon with three bars) in the top-right corner, choose "customize", and you should see a screen with a bunch of icons. Find the one labeled "bookmarks menu", and drag it up to where the other icons are. If you're referring to the links that appear when you open a new tab, you can customize those as well. Hover the mouse over the links, and click "edit". Hover over a link and click the "X" button to delete it, or click "add" in the bottom-left to add another link. Let me know if you're referring to something else - there are a bunch of ways to access favorites in Firefox, and I'm not quite sure which one you're referring to.
