Firefox for iOS doesn't have a lot of menus. The interface that I have discovered so far is: * Tap the address bar to call up the home screen (also called the Awesome screen) to access history and bookmarks. More info: [[Awesome screen on iOS - access search and favorite sites in one place]]. * Tap the tabs icon (a number on a stack of tabs) to display the open tabs list and you can find the gear/cog/wheel icon for settings on this screen. If you discover anything else, I'd love to know about it.
