If you are one of the few who just love to hand on to the 3.6 era, I have some real bad news for you. 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 switch over being pegged as early May. Mozilla stopped short of giving a date for you to deliver its farewells.
So enjoy your time when you have it.
