As Mozilla finally nears completion of the next generation of its popular open-source browser, the beta version of Firefox 4 begins to solidify into its final form. In the latest Firefox 4 beta, the browser focuses on faster start-up times brought by making improvements elsewhere in the code.
A new database standard has also debuted in the latest Firefox beta. Called IndexedDB, the technology replaces Web SQL and has been extensively used for managing user data in offline situations.
A final and minor change to Firefox 4 beta 9 brings the tab bar up a few pixels, so it now sits on the same row as the Firefox menu button. The top of the browser now looks extremely similar to Opera 11 and Internet Explorer 9 beta. The full and technical change log for Firefox 4 beta 9 is available here.
