Nine months ago the official launch of Chrome Extensions marked a significant milestone in its competition with Firefox. Now Lifehacker is reporting a significant shift in it’s readership from Firefox to Chrome. What struck me, however, are the areas where Firefox still wins, including extensions like Firebug, NoScript and Adblock Plus. I now use Chrome for UIs like GMail, Yahoo Mail and Outlook Web Access, but improved speed is not enough incentive to wean myself onto a new set of browser features and extensions for general use.
