Mozilla announced today that the latest version of Firefox which is being beta tested right now, called Firefox 4, 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.
All in all this new version of Firefox will most likely solidify and continue it’s popularity. It’s really looking good so far!
