Mozilla has "temporarily" blocked the Flash multimedia player on its Firefox browser following a security alert from Flash's maker, Adobe Systems.

The move to block Flash comes after security weaknesses in the browser add-on was revealed in documents stolen from the Italian security company Hacking Team. 

One of Hacking Team's tools stolen in the hack is aimed at taking advantage of a previously unknown bug in Flash to hijack targeted computers.

While Adobe Systems said last week that it would patch the security flaw, the Firefox block includes even the most recent version of the plugin. 

Alex Stamos, the new head of security at Facebook, called for the end of the animation software in a tweet on Sunday. 

Elsewhere on Twitter, many pointed out that the iPhone was released without Flash support and that Steve Jobs wrote that "Flash falls short" for browsers in the mobile era

Plugins like Adobe Flash can be disabled or uninstalled in the "add-ons" or plugins settings of your browser.
