Mozilla dispatches Firefox 3.6, fills its chair with version 13 beta

If you've been defiantly clinging onto Firefox 3.6 by your fingertips, bad news. Mozilla is officially putting it to sleep -- whether you like it or not -- by auto-updating users to version 12. You've still got a few days to bid your emotional farewells, with the switchover being pegged as early May. But, the browser's creators stop short of setting a date for you to get the flowers delivered by. Official support for the 2010 release finished this week, and the final bout of security fixes was back in January. At the other end of the spectrum, Firefox 13 wobbled up onto its beta legs yesterday, bringing a new homepage, Google's new SPDY protocol and tab extra features with it. If you're making the leap, don't panic if you find some old friends missing.
