Firefox for Android doesn't have toolbars. Instead, common functions are accesible by touching the three square icon (at least on Ice Cream Sandwich). You may type a direction by touching the title bar, and add or navigate through tabs on the icon next to the title (before the menu icon). To go back, just touch the back icon on the bottom (on Ice Cream Sandwich) or the back button of your device. Please note Firefox for Android is a stripped version of desktop Firefox and will not offer all the features Firefox for Windows offers. Also note that you can't use shortcuts or add custom extensions (extensions are commonly system-dependent, and there are too many Android versions to guarantee compatibility).

The Android operating system does not provide the traditional File, Edit... menu arrangement because it is a touch based operating system. Like Firefox on the other desktop operating systems Firefox attempts to make design decisions to fit within the interface guidelines of the Android operating system.

Thanks for the heads-up
