Firefox browser now blocks Adobe Flash by default


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 Is it high time that Adobe finally consigns Flash to the outdated technologies bin?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.

Flash Plugin Blocked

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!

Firefox is now the odd one out….

Its very strange – in the past it was always Internet Explorer and its CSS rendering that was out of sync with all the other browsers, but now – shock horror – it is Firefox that is the nightmare browser!

I have been developing a new web-application called Infacture ( and it renders perfectly in IE 8 and 9, Safari on the PC, Safari on the Mac, Safari on the iPad and Google Chrome… yet in Firefox 4 it does something very strange with padding, and doesnt seem to have even basic CSS3 support like in IE9 and Safari.

Firefox’s rending of div’s and in particular putting padding on the outside rather than the inside, plus its seeming lack of knowledge about putting margin-top:auto; margin-bottom:auto; to provide perfect vertical centering is a disaster when it comes to cross-browser compatability. Its now at the point that I am considering saying that the app supports all browsers EXCEPT Firefox.

Firefox – get a move on, or you are going to get left behind!
