Still use it?
Does anyone still use flash? I haven't had it installed since Adobe dropped support for Linux. There's no real good reason to have it installed. Youtube and co all work mostly on HTML5 now which means they don't require flash.
Unless you want to play old flash games like "Kill Kenny" or "Strip That Girl" there is no reason to have flash installed these days.
If your applications still require flash, time to either find new ones or take the source and upgrade them.
