Before you start hounding the crap out of users to upgrade to your latest version of Firefox, try to consider that not every user is loaded and sporting the latest OS and apps on their computers. In fact the unemployment rate - just those still receiving unemployment benefits (all those who have exhausted benefits are not counted)- is at an all time high so I think I am not alone in complaining that you have not made an upgrade of your product that is compatible with older operating systems. Yet I get constant reminders to upgrade to your latest version, which I can't and it pisses me off!
