On 22th February 2012 Adobe released a post on their blog sayin’ that Flash Player releases after 11.2 for browser will only be available within Google Chrome browser distribution (no longer as direct download from adobe).
Oh, yes… just for Linux… but honestly who cares?
I have already ditched any site that is “usable” only with flash. (And yeah… youtube can provide videos through html5 video capability or old flash player versions.)
