Mozilla’s Flash-killer ‘Shumway’ appears in Firefox nightlies
In November 2012 the Mozilla Foundation announced "Project Shumway", an effort to create a "web-native runtime implementation of the SWF file format."
Two-and-a-bit years, and a colossal number of Flash bugs later, Shumway has achieved an important milestone by appearing in a Firefox nightly, a step that suggests it's getting closer to inclusion in the browser.
I was unaware Flash needed a 'killer' at this point.
