New Default: Mozilla Temporarily Disables Flash In Firefox

Trailrunner7 writes with news that "Mozilla has taken the unusual step of disabling by default all versions of Flash in Firefox." Two flaws that came to light from the recent document dump from Hacking Team could be used by an attacker to gain remote code execution. From Threatpost's article: One of the flaws is in Action Script 3 while the other is in the BitMapData component of Flash. Exploits for these vulnerabilities were found in the data taken from HackingTeam in the attack disclosed last week. An exploit for one of the Flash vulnerabilities, the one in ActionScript 3, has been integrated into the Angler exploit kit already and there's a module for it in the Metasploit Framework, as well. Reader Mickeycaskill adds a link to TechWeek Europe's article, which says these are the 37th and 38th flaws found in Flash so far this month, and that the development "is a blow for Flash after Alex Stamos, Facebook's new chief security officer, urged Adobe to set an 'end of life' date for the much-maligned software."

      If the crap that Flash does is part of the HTML 5 spec, I really do worry we won't be able to block it quite so readily.

      Amusing but true, there's already a lot of HTML5 nonsense that goes on in many sites, even on browsers I specifically disallow Flash on.

      I think what we need to advance user tech is "click to remove HTML5 element" with memory of what element you removed, that would automatically be scotched the next time you visited the same site. That way you could even allow "tame" ads if you liked, and just stop obnoxious floating elements that blocked content...

      I have used flashblock to control the flash player. Note the only reason I installed it was to stop autoplay flash. I can't really focus on anything else when a video is playing. With the implementation of flash blocking on Firefox, which stated, what, a couple months ago, flash no longer works at all. Flash has been on the decline since the smart phone did not have the power to run it and everyone is blocking it. Which, as mentioned, is a moot point as HTML5 provides autorun ads that have no control. The sad thing is that Flash actually is a very good tool for doing some very useful things. Unfortunately, the only profitable thing it was ever good for was packaging ads.

They didn't really block "all versions," they just blocked versions less than or equal to known vulnerable versions, which at that time happened to also include the then-latest version.

    Chrome can block popups, that Firefox lets through. This is because Flash is doing the popup, and Firefox does not catch the CreateWindow, but Chrome does. Firefox only intercepts the normal web window creates.

    Yes, that was the narrative at the time - 'they are taking away our freedom'. In hindsight, even though I probably would have heavily criticized Apple for the move, and would have pointed to it as a reason to choose Android, the reality of the situation was, at least in my experience, that Flash on Android was a rather shitty experience that never really worked that well. And while it seemed arrogant and annoying that Steve Jobs tried to use his sway to annihilate Flash as a platform, I now believe that it was for the best. Flash has a heavy impact on battery life, is generally a lot slower, and is generally less secure than native alternatives.

    So, yes, Apple made a seemingly arrogant move and exiled Flash from the iOS platform, but in the long run this drove development toward alternatives and pushed web developers to use technologies that were more mobile friendly (like using HTML for your content instead of some flash application) and I think the overall net effect for the web community has been positive.
