Facebook's head of security is the latest to join the chorus calling for the death of Adobe Flash.

In a pair of tweets over the weekend, Facebook chief security officer Alex Stamos called for Adobe to pick a date to end support for Flash and for web browser makers to drop support the same day.

Stamos' comments followed the revelation of two previously undiscovered security vulnerabilities in Flash as part of a leak of security company The Hacking Team's internal data. But calls for the end of Flash date back much further. Steve Jobs famously penned a diatribe against the platform in 2010 following Apple's controversial decision not to support Flash on the iPad. Since those days, many sites, such as YouTube, have shifted away from Flash and towards HTML5 and JavaScript-based solutions.

Facebook still requires Flash to play videos on some browsers, but Stamos indicated on Twitter that the company is working to make HTML5 video available to all users.
