Tap on the address bar and type about:home in the address bar. That will bring you back to the home screen.

It can also be opened by closing all open tabs by swiping them off the screen or tapping the close button.

Do you have Android 4.0 or later? There should be a vertical stack of 3 small squares to the right of the address bar that calls up the menu. Can you find it?

Regarding the home page, I don't think you can change the start screen design yet. I bookmarked the start page (about:home) so I could get back there quickly. Not sure if there is a better shortcut.

Thanks for your responses.

To preface the rest of my message, I Love Firefox on my desktop and laptop. It's the only browser I would ever consider using. But after messing around for way too long with Firefox on my phone and getting really frustrated, I ditched it and tried Dolphin. I was instantly pleased and learned the navigation without any effort or looking up anything. I'd never even heard of it before (not a techie, for sure). Super intuitive, streamlined and easy to figure out and configure just how I want it. So I found what I needed.

Thank you
