Firefox 4’s New User Interface

Firefox 4 is available now!  Here’s a video introducing the new user interface, and the fantastic UX team that designed it.





  1. Hi,
    I am long time user of FF and FF4 is really good … but …

    Why do you loose an entire line in top menu just to let me know that I am on FF ?

    A nice icon is enough!



    PS: Chrome has not made that error.

  2. How on earth do I turn these silly dialog speech bubbles off and go back to simple dialog boxes?

  3. I love the new Firefox, but how it’s possible that we can’t save our tab groups on Panorama view ? If I close the browser, all my groups are gone ! I think is useless without a save feature.

  4. Great video, really well done.

  5. Glad to see you guys live and in color for once. Although I do not agree with each decision you guys made for Firefox 4 the overall impression is rather good. Looking forward to your future work. :-)

  6. congratulations Alex and team – keep up the good work!

  7. Gotta say, I’m really enjoying the finalized look, although I wish we could have gotten more posts from you regarding the process of refining the finished UI. :P Although, of course, it’s not too late to give us a “Designing Firefox 4” retrospective…

  8. I don’t understand why when you right click on a link, the two options of opening in a new window and opening on a new tab has been switched around since the last version. This is particular annoying when you are used to right clicking and selecting open in a new tab, without having to think about, and now it opens it in a window. Come on!

  9. How can it be, that when there’s actually people responsible for the look-and-feel, with FF4:

    – F6 no longer works with Tabs on Top
    – You stole Ctrl-E from Windows users for Panorama, then implement Ctrl-Shift-E instead (!!!)

    There is a good reason people don’t use Ctrl-L and Ctrl-K, and it seems silly I would have to explain this to a Principal Designer, but…

    Most people run Mozilla on a PC, are right-handed, and use a mouse. Feel free to familiarise yourself with keyboard layouts ( and come to the conclusion, that for Latin script based keyboard (note: this includes China and India) Ctrl-E is conveniently placed on the left side.

    Bring back F6 for Tabs on Top, restore Ctrl-E and while you’re at it, fix Ctrl-W for closing Tabs if you’ve touched embedded flash players (like Google Chrome).

  10. Firefox 4 is very nice but it has some deficiencies.

  11. I am stoked. Can’t wait to download Firefox 4 :D

  12. I’ve downloaded it and i am loving it however there are certain plug-ins that does not work with the latest update but i am sure the developers will be keen to update their plug-ins as the browser has surpassed my expectations.

    I love Firefox 4!

  13. I have to confess that I do not see any of the changes to the interface as an improvement. The use of color has been lost, so it looks very clinical and drab. I do not want to lose the menu bar for a button. I do not find tabs on top to be more logical in any way. I find the other things discussed in the video such as app tabs and sync to be totally incomprehensible. The only thing I agree with is that you are correct in suggesting that many (but not all) of the things that have been changed can be changed back. I think it is a shame to have to rely on a 3rd party theme to get the familiar FF 3.6 look back – that should have been a native option within the program.

  14. I absolutely love the new Firefox look. Sleek, stylish, clean, and streamlined. My favorite part is being able to get rid of the bottom toolbar.

  15. If you are in uncomfortable position and have no money to get out from that point, you would need to receive the business loans. Because it should aid you emphatically. I get short term loan every time I need and feel myself fine because of it.

  16. The submit article service and article submission sites used to be the popular option of different people. Thus, you should take that for your hot release close to this good post.
