Actually in Firefox for Android you can't turn any website into homepage like Firefox desktop browser, rather you can customize the order of the panel (i.e. Bookmarks, top-sites, history etc ) you see when Firefox for Android opens. To do so just follow these steps: # Tap the Menu button (either below the screen on some devices or at the top right corner of the browser) and select Settings. # Then tap on Customize > Home # Now here you can chose which panel will be in front when you start your browser or which panel you don't want to show up. # Just tap on any panel name you'll get the option.
