It seems that the Lamarck’s theory of evolution had its effect on the new interface of Firefox 3.0. The most used parts have grown and became visible more than the unused part that have shrunk.

In most browsers we have seen the back and forward button has equal size and same design. This time, Firfox interface designer had said it loud and clear, the most used button in browser is the back button. The rest are rarely used. Therefore we made it big for you. I think it’s true. For example I never use the forward or home buttons. But I think the refresh button is commonly used one.

This is a very interesting case in user interface and usability design. It takes human behaviors and experience into consideration. And in some way it’s so similar to the theory of evolution. Functions are not only pure actions, its also behaviors and habits. Design is not only neatness or arrangements, its serving behaviors and experience.

    I’v tried firefox 3.0 and i have to be frank, other than changing some ui elements i haven’t really touched the differance between it and its previous predecessor firefox 2.0.

    don’t get me wrong I love firefox, butttt i was expecting something alot more from v3.0, maybe some cool new features are still hidden from me I dont know.
    thx for the share

    c’mon guys, you cant see the new features………!
    what about the auto-complete address bar, which gets links from both history and bookmarks, that alone made my life easier, plus the main changes in FF3 were PERFORMANCE changes mostly, memory leaks ….

    nice blog by the way

    The biggest Back and Forward buttons I’ve ever seen where the ones on IE3.0. After that they started getting smaller and rounder. But the thing that ALL browser UIs suffer from apparently is wasted space. This space can’t be used for anything. With the exception of Opera and Google bar, just about everyone else has a ton wasted -dead- space in the UI that can’t be used to display anything. I guess they expect everyone to be running on a duel 3000×2000 32″ screens these days

    Other than that, I love FF3, I think it has come of age. It is the real challenger to IE

    Well! I guess it’s true about the back button! and I do use the home button to get back to Google and start searching! and the Reload button! Thanks for the F5!

    I am sure there is a lot of new features on FF3, but i think this is the first time you see that a back button has a different design than the FW button :)
