Mozilla: All Versions of Adobe Flash Now Blocked From Firefox Browser by Default, Company Says
Firefox executive Mark Schmidt announced the change Monday in a social media post. He said the browser is blocking the platform due to security vulnerabilities.


I wonder if this is why Apple/MAC has been so distanced from FLASH over the years...

"Thoughts on Flash"[edit]
On April 29, 2010, Steve Jobs, the co-founder and chief executive officer of Apple Inc.,[1] published an open letter called "Thoughts on Flash" explaining why Apple would not allow Flash on the iPhone, iPod touch and iPad. He cited the rapid energy consumption, poor performance on mobile devices, abysmal security, lack of touch support, and desire to avoid "a third party layer of software coming between the platform and the developer". He touched on the idea of Flash being "open", claiming that "By almost any definition, Flash is a closed system".[2] Jobs tried to dismiss the idea that Apple customers are missing out by being sold devices without Flash compatibility. He quoted a number of statistics and concluded with "Flash is no longer necessary to watch video or consume any kind of web content."[2]
