Experimental Firefox Builds Put Tabs on the Title Bar (Available for Download)

Firefox 4.0 was supposed to be feature complete at this point while Mozilla worked towards the final version release, but that may have changed. Developer Bill Gianopoulos has been working on experimental builds that bring the tabs into the title bar along with other bug fixes.

From Bill’s website: These builds are essentially the same as the corresponding Official Trunk Nightly Builds with the exception of the inclusion of patches for some outstanding issues, including not yet landed fixes for some MathML issues, and User Interface changes planned for Firefox 4, as well as bugs that I am currently working on or find particularly annoying.

Here is a closer look at the combined menu button/title bar/tabs setup on a maximized window. The potential to really condense the UI is there if you want and/or need it…

Note: We chose to keep the Bookmarks Bar visible on our system.

The tabs return to their regular position when the window is not maximized.

If you are feeling adventurous and want to try the new UI feature out, then pop over to Bill’s website to grab your own copy. Keep in mind that unless you “embed” the experimental build within a portable framework it will have access to your regular Firefox profile.

Want to set up your own portable, contained version on Windows? Here is how to do it:

1. Download the zip file version of the experimental build from Bill’s website and unzip the contents.

2. Set the experimental build folder to the side for the moment.

3. Visit and download Mozilla Firefox, Portable Edition (link provided below).

4. Extract the portable Firefox from to your desktop or another convenient location.

5. Expand the folder structure for the portable Firefox as shown in the picture below and delete the contents of the Firefox folder.

6. Transfer all contents of Bill’s experimental build into the Firefox folder.

7. Start having fun with your new portable experimental build!

Note: Downloads are available for Windows (32 bit) and Linux (32 & 64 bit) platforms at this time.

    that’s just like Maxthon 3

    Looks like Opera no sh*t

  3. TJ Fadness

    @Sid: If I remember right Opera copied some of the Firefox concept art from way-back-when…

    Anyways, it’s about time! I’ll wait for them to add it to the beta so I have at least /some/ stability for now.

    I hope it will be a part of the default Firefox 4 UI

  5. TJ Fadness

    @Eeki: I’m pretty sure that’s the intent!

    They are copying Chrome in a lot of ways, and it acts exactly like this.

    Sure, they are copying Chrome a bit, but that’s good! It means you have maximum screen real-estate for actually browsing.

    finally I can stop use that userChrome.css trick to move this button ;-)

    I would hate to have my tabs above the URL line. Can’t understand where there would be any advantages.

    Being a fan myself, wouldn’t you have to alter some of the code within the ini files of the FirefoxPortable in order for this to work? The original ini will be configured for Firefox 3.6 wouldn’t it?

    @Ronnie – No, you can just drop this experimental build in and start enjoying it no questions asked. ^_^ That is one of the beautiful things about the build of Firefox…I keep an “empty portable hull” ready to go just for stuff like this. ^_^ It will of course display the bookmarks that come with the portableapps build, but then again that information is located elsewhere besides the folder you are “modifying”. ^_^

    Interesting – I’m running Firefox beta 8 in Ubuntu 10.04, and my tabs are next to the Firefox button. (I actually just discovered that – thank you Mozilla for finally giving Linux users the firefox button!) I do have a title bar above that where my close/minimize/resize buttons are, as well as the title (obviously).

    I just played with it a little more and if you go to Preferences – Toolbar Layout you can pretty much do whatever you want. I smushed the navbar stuff and the tabs all into one line. Not sure if I’m going to keep it, but it does leave a lot more room.

    The waiting for a stable FF4 is killing me.

  13. matthewguay

    It’s really sad to see Mozilla fumbling almost as bad as Microsoft in the browser wars 2.0…

  14. matthewguay

    Meaning, FF 4 should have been out long ago! :)
