Mozilla has been working hard on giving Firefox 4.0 a facelift. Stephen Horlander, who has been a long time Mozilla contributor, has shared some more information about the upcoming user interface (UI) changes.

Firefox 4.0 Mockup
The new skin will eliminate the Menu Bar and instead tuck away all the options within a single application menu. This is similar to what you may have seen in Windows 7 applications like Paint and WordPad as well as the recently released Opera 10.5 pre-alpha.
The other big change in Firefox 4.0 will be the placement of the tab bar. According to current plans, the tab bar will be now positioned above the address bar. However, the tab bar will not be merged with the title bar. The title bar will be retained in order to house the application button. There will be numerous other changes all around including new icons and refined toolbar appearance.

Firefox 4.0 vs 3.5
The Firefox 4.0 UI is still a work in progress. However, it is definitely shaping up to be an impressive update to the existing skin. What do you think about the changes? Do you prefer having a simple single menu instead of a menu bar? Don’t forget to let us know.
