Adobe Flash is now blocked by default on all Windows and Mac versions of the Mozilla Firefox web browser. Is it high time that Adobe finally consigns Flash to the outdated technologies bin? Is this one security flaw too far? How great would it be if Adobe instead devoted their efforts to developing tools for HTML 5 and CSS to achieve similar moving vector functionality that attracted web developers to use Flash in the first place.Following in the footsteps of Apple (in which Steve Jobs wrote a then controversial open letter in 2010), Mozilla is yet another company who has publicly raised serious concerns with the lack of security and widely documented bugs in Flash.Mozilla has unearthed evidence showing that the bugs in Flash were being actively used by criminal groups to exploit users and install malware and ransomware on their machines. At present the exploits were limited to FireFox installed on Windows PC's.On their support pages Mozilla said that the block would remain until Adobe releases an updated version to address known critical security issues. A similar block has been built in to the Apple Safari browser since version 7 in 2013.My verdict: It's time to pull the plug on Flash once and for all. Come on Adobe, think to the future instead of frantically patching the past!
