Mozilla wants Firefox 4 user interface to be minimal with less controls much similar to Google Chrome and there will be no Menu bar in upcoming Firefox 4, two tiered menu in nightly builds looks similar to Windows Vista menu but can’t confirm this design will be final.
Mozilla’s director of Firefox Mike Bletzner says in on new Firefox menu design that “the goal is to put the mostly used controls in a single menu, and return vertical space to the web content area by removing the pixels otherwise taken up by the menu bar”.
In Firefox menu first column shows mostly used controls New Tab with another sub menu, Start Private Browsing and other controls users use most .
Second column shows Bookmarks, History, Downloads , Add-ons, Options,Help submenu contains Help, Getting Started and About Firefox, Troubleshooting Information, Release Notes and Check for updates will be located in about window.
