Many websites are telling me that my Firefox 3.5.16 is too old. PayPal was doing so until Debian security pushed a patch which seems to have removed that error but Gmail, for example, still complains about my browser version.

What’s wrong with Firefox 3 all of a sudden? Some massive feature it’s missing? The Any Browser Campaign, admittedly intended for the 1990s browser wars, finds new relevance in the world of HTML5.
