Mozilla blocks all versions of Adobe Flash in Firefox

Mozilla has added all versions of Adobe Flash up to the most recent version 18.0.0.203 to the Firefox blocklist.

Security researchers have discovered vulnerabilities in recent versions of Adobe Flash that have not been patched yet by Adobe but are exploited in the wild. In particular, several exploit kits are already making use of it to serve crypto-ransomware to systems running Adobe Flash.

In an effort to protect Firefox users from harm on the Internet, Mozilla has added the current version of Adobe Flash and all previous versions to the browser's blocklist.

The blocklist lists browser extensions, plugins and other components that are blocked automatically by Firefox either directly or sometimes in the case of plugins, by setting them to "ask to activate".

The Flash vulnerability affects all versions of Flash on Windows, Linux and Macintosh systems.

Firefox displays a warning message on its plugins management page that Flash is vulnerable. As you can see on the screenshot below, Shockwave Flash has been set to "ask to activate" and not blocked permanently.

firefox block flash

The difference between "ask to activate" and "never activate" is that Flash is not blocked completely in the former state which means that Flash contents can still be accessed in the browser. While that requires an extra click, it ensures that code on websites cannot exploit the vulnerability automatically without user action.

Options to switch the state are not available due to Flash being on the browser's blocklist.

Firefox displays a warning in the browser whenever Flash contents are embedded on a web page:

Firefox has prevent the unsafe plugin "Adobe Flash" from running on [website url].

flash blocked firefox

The prompt displays options to allow the plugin on the page. If selected, Flash contents will be loaded and can be used just like before.

The blocklist update may not have been deployed on all Firefox machines. You may request a manual update of the blocklist at any time using the method below:

  1. Open the Web Console by tapping on Alt and selecting Tools > Web Developer > Web Console (or use Ctrl-Shift-k).
  2. Click on the preferences icon.
  3. Locate Advanced Settings and check "Enable browser chrome and add-on debugging toolboxes"
  4. Open the Browser Console afterwards with a tap on Alt and selecting Tools > Web Developer > Browser Console (or use Ctrl-Shift-j)
  5. Type Components.classes["@mozilla.org/extensions/blocklist;1"].getService(Components.interfaces.nsITimerCallback).notify(null);

The blocklist should update if updates are available. If you have Flash installed in Firefox you should see the vulnerability warning now in the plugin manager of the browser.

Additional information about the blocking are available on Bugzilla@Mozilla.

    Firefox might block it but there are problems with Adobe Flash Player because some versions just won’t install. Even if you do a clean install, they just won’t install and you have to wait for the new version. What’s the deal with Adobe Flash Player? Is there an alternative because it’s a headache to update.

    MOZILLA FIREFOX HAS SOLD OUT! They have become another Explorer/Chrome. Another look-a-like/do-a-like!. Never have liked Microsoft’s Explorer nor do I like Google Chrome. Don’t like the way they,re set up and both have blocked me from various sites. They look pretty much like the same browser. Firefox use to be for the people but these days I’m not so sure,.. They are looking and acting more and more like the other two! It should be “MY” decision what In want to run and/or where I want to surf not some corporate developer! If my computer gets messed up – that’s on me! I’ve fixed it before and I’ll fix it again if i need to! And as far as Flash being vulnerable – heck (I’d use a different word here) it doesn’t matter what the app/program/software you’re using, if you’re connected to the web, they’re “ALL” vulnerable! Don’t kid yourself and don’t let an one tell you otherwise! Don’t be fooled into a false security. “EVERY” firewall/malware/spyware/whatever program is vulnerable! There is “ALWAYS” a backdoor! The only way a computer computer can not be vulnerable is to disconnect! (which I won’t do. I like to explore) Blocking Flash is only one of Mozilla’s recent evils. They fought for years against putting any form of DRM into code, however, recent Firefox versions in options/content there is a new box “Play DRM content” which, by default, is checked on. Their reasoning – Netflix won’t work on Firefox without it. This is an out right LIE! I have never had a problem watching Netflix! I expect that option will soon go the way of flash and not an option. AS Not Happy stated above, you can not activate flash, I have v.19.0.0.2…! You can press keys/click your mouse all day long and it won,t be activated. And, at this time, changing browsers is not an option. For now, Firefox is the least of the evils. But I am looking!
    FYI: HTML5 has DRM written in its code

    I answered this comment back on version 39 of Firefox, and am now on 40.0.3, and if I get a page that Firefox that doesn’t want to open properly, you can right click on the page and select open in Chrome. I actually had to install Chrome Canary since chrome itself had a problem in August 2015. So now there are a lot of pages that I just right click and get into chrome and do what I need to do. That is courtesy of Firefox’s “Nanny” complex.

    What a bunch of whiners who post comments on this site. They get protected from serious vulnerabilities, & complain if it inconveniences them. As was written in the article, it only “asked to activate” & didn’t completely block Flash. Adobe released a fixed version soon after anyway, & was easy to download & install. Two weeks after the whiners posted here, it’s up to v18.0.0.209 (actually it already was some time ago), & runs quite happily in Firefox.

    I have been with Firefox for lots of years, but this may be the final straw. I just went to Chrome to watch a You Tube video since Firefox blocked it. It ran just fine and my computer was not compromised since I have a good firewall and anti virus installed. If they don’t do something about correcting this they may find themselves on the outside looking in on the Internet. I have version 39, and would like to revert to a previous version, but may have to just go Chrome to get away from the Big Brother aspects of Firefox.

    Blocking Flash is making the dying of Firefox faster. I hate x 100 to click every time I need to see the Flash content on a webpage. Of course, I hate Chrome too, I won’t move there. I will try some other browsers.

    Is anyone here familiar with Clipstream?

    http://www.dsny.com/clipstream

    It is an alternative to Flash and HTML5. It is an instant play video streaming service that requires no plugins. The technology features security such as watermarking, host-locking.

    The company on its website claims it is “disruptive,” meaning it will disrupt the video industry. But it doen’t seem many are famialiar with it or are using it. It has been around for a year, but it was just release as a cloud based service.

    Check out some of the videos. I would be very interested in hearing pros and cons.

      According to the following video, it is for corporations who want to protect their videos.
      http://dsny.com/node/1673

      It’s too early to tell, but I don’t see this ever replacing HTML5, at least not for regular
      home users. As a user, sometimes I want to download a video for personal reference,
      without intentions for sharing and copyright infringement. Clipstream does not allow
      that.

      Indeed, at the time of writing, my Flashgot extension was only able to detect the Ogg
      Vorbis audio track in the video linked above. Obviously it’s doing its job, but as a
      workaround, I can make screen cast using a program like CamStudio if I wanted to
      capture the video.

      What I’m trying to say is that there will always be someone who will try to work around
      restrictions.

    Firefox, what the fuck is wrong with you? I can’t use the internet because of this bullshit, and neither can any of my clients. You just destroyed millions of people’s internet usage; no “security hole” in Flash Player could possibly be worse than that. Let me decide whether I care about Flash Player updates; it’s none of your damn business. Why isn’t there a togglable setting to just hide all security warnings for the Flash Player plugin?

    PLEASE PLEASE PLEASE just let me install updates manually once or twice a year when I feel like it, and make your software shut the hell up about how it’s out of date. None of these “security holes” are nearly as big a problem as not being able to use Flash websites. Flash Player releases thirty updates a day and installs McAfee on people’s computers if they’re not paying attention; anyone who lets it update itself automatically is insane.

    The idiotic warnings about Flash Player vulnerabilities that make people click through them (on a per-website basis) (that erase their “don’t ask me again” status every few days) were enough to get me to move several of my clients to Chrome last month. Tonight I’m moving everyone.

      Hey, don’t hate on Mozilla. The far, far more annoying problem with Flash is that thousands of web sites and their lazy web designers use it for useless, annoying animation and obsolete audio/video players.

      Please everyone, just make up a simple cut/paste feedback text for web sites that still use Flash:
      “ESCALATE TO RESPONSIBLE MANAGER. I am no longer visiting your web site until you purge Adobe Flash based function from it.”

        The only “obsolete” thing here is Firefox, do audio/video players need upgrades? Just to keep old hardware from working properly and forcing you to upgrade something every other day, or maybe to have a button of “share” and “buy” and what not . And not just browsers, I could still live happily with Windows 98 and Office 2000 before the ‘redesigning’ . Firefox sucks now!

    Kill Flash and Java, the two biggest security risks on Windows. Embrace HTML5. Once they are dead, Microsoft should buy Adobe and drop the price of Acrobat Pro down to $19. With the Surface 4 and the Ntrig pen, Surface would be an artists dream! Adobe Creative Suite would continue to run on Apple, of course.

    For those on Windows, just use Ninite Flash Player installer.
    It took 2 minutes to update Flash Player to v18.0.0.209. If you
    are unfamiliar with Ninite installer; you can use this same installer
    countless times in the future.

    Side note:
    Please ignore the fact that I accidentally uploaded the executable
    to vmware-related-files downloads repository. It was a daft move,
    but as the saying goes, we live and learn.

    Our household has been flash-free for over six months. If a website doesn’t have HTML5 video, it doesn’t get played here.

    I especially like sites that instantly demand I install flash as it is telling me to leave right now.

    About the only good thing I can say about firefox (use Pale Moon) is this is a great move and hopefully those flash–dependent sites will hurriedly convert to HTML5.

    As another poster noted above, I too began removing Adobe PDF reader (use SumatraPDF) , Adobe Air and the full Java-junk several years back. Having NoScript in Pale Moon adequately secures me from the javascript issues. Oh and on the subject of security, dd-wrt on all my routers.

    Nothing is perfect but I feel I am close to the pointy end of self-protection. :)

    Flash is pioneer and crucial in free games, not immorally “downloaded” (say STOLEN) games. Just go ahead and block the entire internet, since that’s what’s causing all the phishing and scams, corrupt bastards.

      Agreed, OTT, but he’s not the only one. There’s a whole community of creative people who could create amazing beautiful things in a tool that combined code and creativity. They’ve had their brushes taken away and nothing in the HTML5 world has come close to opening up that world of creativity again. The internet has become mostly flat, square, and boring, and sure, more secure w/out Flash. And yes, there are some AMAZING HTML5 pieces out there, but the LOE that goes into them is staggering compared to what could be done in Flash.

      Flash (well, to specify, the swf… Flash itself is still a pretty wicked program) is on it’s way out, there’s no doubt, but to ignore the benefits that have been lost to the creative community is ignorance.

      Yeah, same here.

      Flash is a bigger problem than PDF readers though, because with PDF readers I can install a different PDF reader on say my parents machines and forget about it. With Flash, although I can disable Flash on my computer, and if need be re-enable it when needed, deciding what to do with my parents computers is more problematic. If I disable it, then when they visit the BBC it will tell them to download and install Flash. If I make it click-to-play, it will just be an annoyance and they’ll just get into the habit of clicking ‘yes’ every time anyway. So, we really need all websites to ditch Flash, but at the moment we’ve still got sites like the BBC and education sites using it, which creates a problem.

      The main reason you can still watch You Tube videos is that they have now switched the majority (if not all?) videos to HTML5 format and I like it better. It does not rely on Flash at all. This was really pushed and will continue to trend up elsewhere. Another reason besides the security holes of Adobe Flash is that Flash format drains batteries on mobile devices much more quickly.

      If you have Flash Player installed (any version all the way up to 18.0.0.209 which was released just hours ago it seems) then yes, technically you’re vulnerable to some of these new hacks. Because you’re watching video(s) from YouTube the chances of anything going awry are fairly slim since YouTube creates their content from user supplied videos. I think it’s safe to say that yes you’ll be ok IF you just use Flash to watch YouTube videos, but I won’t speak or even guess the risk for any other websites out there (and I can’t guarantee that even YouTube is perfectly safe at this point, it’s just a fair level of certainty).

      Flash is vulnerable, period – if you use it or have it enabled in your browser then you’re potentially vulnerable and there’s no getting around that fact.

As it is it I cannot view footage of Hurricane Patricia on weather sites. Countless other websites are now effectively CRIPPLED. I have TONS of security, including VPN.
      FIREFOX, CHANGE THIS NOW!!! OR LOSE TO ANOTHER BROWSER. IT’S THAT SIMPLE!!

        I saw a recent study review on popular Browser Sites which said Mozilla Firefox has been steadily losing ground verses the interests of it’s users. http://www.richmedia.com/richideas/articles/browser-wars-continue-in-2015-chrome-in-the-lead Both Firefox and Google Chrome will cease Browser plugins by early 2016.

      If you’re happy for your PC to become part of a Russian botnet, or exercise your inalienable right to have your online bank account emptied, just click the button to re-enable the insecure and dangerous plugin everywhere. It’s a lot quicker and easier than whining on the internet about it.

      Chrome dumped Adobe Flash, Silverlight, Java and other plugins to paranoidly overprotect users ages ago, and absolutely every sane person (outside Adobe and stone-age game/porn sites) agrees that Flash, which has been plagued with issues for years, should have died a death a long time ago.

        When I go to Youtube, I get the Flash Player security warning that won’t let me play videos unless I click a hidden button in the background of where the video should be. Far more commonly, things like advertisements on all sorts of sites everywhere use Flash, and show the same security warning in place of the ad. Because of that, I’ve gotten over a dozen calls today from panicked clients who can’t deal with error messages showing up while they’re trying to surf the web, and are convinced that their computers are under attack. It’s only noon. I shouldn’t have to deal with this shit.

        I’m surprised to learn top video sites like Vimeo and Dailymotion “don’t exist” in your universe since they, like Youtube and Netflix, by far the most popular ‘flash sites’ that you listed, have non-flash video. In fact the most popular flash-only video sites on the internet are porn sites.

        Of course, as with IPv4, there are always going to be dinosaurs unable or unwilling to change, hanging on to technologies and systems with no future and making internet users suffer because of it.

        Instead of waiting for Adobe to announce the burial of Flash, as Facebook suggested, browsers should simply set a date at which point they will completely pull the plug on it.

        I don’t know what universe you live in where no one uses Flash, but it must be one where Youtube, Hulu, Netflix, Twitch, Amazon Video, and every other streaming video service on the entire internet don’t exist. And Chrome has Flash Player built into it, so I don’t know what you’re talking about with them “dumping” it.

        The only issue with Flash is the constant updates, and both Adobe and Mozilla demanding that I keep installing them thirty times a day. Almost none of Flash’s updates are even real. They just release fake ones every day because they use their updater as an advertising platform.

        There is no button that universally allows Flash; you can only allow it on a per-website basis. And if you tell it to remember your choice, it forgets anyway an hour later, because there’s another new Flash Player update.

        Heading back to Internet Explorer then, I guess.

        Isn’t Firefox supposed to be the highly customizable browser? Isn’t that its main feature – the fact that you can customize thousands of features in it? Why isn’t there an option to permanently disable all plugin security warnings? I’d rather have 0.001% of my clients get a virus than have 100% of them unable to use half of the internet.

        Web Developers aren’t fighting with compatibility issues. “Web developers” are downloading jQuery and testing only on one platform then IGNORING problems until people start complaining.

        If “web developers” would read what is actually in the HTML5 specifications, how DOM works, and skip jQuery then they’d stop using browser specific non-standard tags that have been causing most of the problems.

        If “web developers” would test in more platforms than their favorite browser, as software devs need to do, and act just a wee bit professional, there wouldn’t be as big of a problem.

        Also, the open source fallacy of “competition kills technological advancement” (a.k.a. “1 perfect browser”) is annoying, stop preaching it.

      Probably, most AV (antivirus) worth their salt have taken samples and pushed out definition updates by now. However, the date when the exploits were discovered is not the same as when it was introduced to the internet. That means for a undisclosed length of time, AV protected machines were vulnerable as if they even didn’t have an antivirus at all. Any major attack nowadays is sophisticated enough to almost guaranteed at least initially to bypass any heuristics or proactive protections AV claim to offer.

      Basically like other said, AV are only minimally effective at best. AV companies react fast when they find the attacks, but like I said they are almost useless when they don’t definitely know about it or have samples to make definitions for.

      Security is a many-layered thing … An antivirus would be one of your LAST lines of defense (if indeed it was able to detect zero-day exploits). If you’re relying on AV to protect you from harmful actions on your computer, in other words, it’s already on your system, then you’ve lost the battle. Better to be proactive and try to close the holes that let it in in the first place.

    Discovering yesterday that latest Flash 18.0.0.203 was again vulnerable was the final straw here. Looks like I anticipated Mozilla’s decision by completely removing Adobe Flash, not only for Firefox but for the Windows’ platform globally : I’m over with Flash, finished. Removed all traces, files and Registry, leftovers after the official uninstall. First surprise was to notice that several sites I believed required Flash for their videos handled HTML5 once they notice Flash is unavailable on the user’s machine. At this point it’s a 80 to 20 relief/handicap. It’s up to the domains still depending on Flash to make the move, and that move will be fast if/when they realize the number of users free of Flash.

        But as there are still idiots complaining about their favourite exploit site with funny videos and false news and crap do not work in firefox.
        For those, and only those, shumway might be a solution.

        Nothing but problems with ”nasty” flash ! They should ban and block java script also as being miss-used big time cosing us problems ! The whole good damn Internet should be rebuilt ! Opening web page should not compromise OS/user and not allowed to tamper with OS in any way !!! And MS does not provide ”secure user space” no access to low level OS ! That i consider using Linux for browsing internet maybe CubeOS or similar ! But that doesn’t solve problems with Firefox ! If then so Firefox blocks flash then alternative must be in place and provided with browser and guess what – it’s not !

        True. Ghacks articled Shumway and that’s when I got to hear about it. Certainly promising but perhaps not yet sufficiently elaborated for me to try it. Later on I guess when it’ll be more mature. Thanks for mentioning it.

      I also found this interesting

      http://secunia.com/resources/vulnerability-review/update-top50/

      It is never “proactive” to block software, Internet Explorer has far less vulnerability reports than Chrome which means Microsoft can “block” chrome and prevent people from using Google’s Browser because it represents a significant security risk to their flagship product, Microsoft Windows.

      In fact, since the majority of infections occur due to tainted web-ads, browser-vulnerability and flash-vulnerability alike, pushing ad-block on people makes more logical sense if all they wanted was to prevent infection.

      But then, like-wise, Microsoft could block chrome and firefox from running on Windows, have a web-ad blocking service with constant updates be pushed into internet explorer, then set up a single loophole for a new product line:

      Microsoft Ad Service, the only Ad service not blocked by Microsoft. Buy your ad-time today!

      Open source is not beyond the corruption of corporate affairs. Don’t blindly support them without understanding the politics behind their actions. This has nothing to do with security, dig deeper.

      Firefox is LYING, you cannot activate Adobe Flash, it is blocked for good.

      It is not preventing me from using many sites that require Flash and to dictate to me what I can or cannot use and do is wrong.

      Take your commie learning and move to China but first unblock Flash.

      Develop your own if you must but till that time allow users to use Adobe Flash.

        Firefox continues to ramble on about Adobe Flash being the security culprit. Meanwhile they sit on their ass and do nothing to offer an alternative Addon. Personally; I like what someone else said; switch to another Browser. That way Firefox might learn what its like to see massive boycotts on their infamous Browser. I’ve always liked the Firefox Browser but boycotting Adobe just doesn’t cut it for me. Where are the ingenious programmers at Firefox making their own type of Flash Addon?

        Just remember, one of the tenets of open source is that any proprietary software is inherently bad and that copying the assembly and distributing as your “new” version isn’t stealing… unless you’re a corporation doing the same thing to open source software.

        This has nothing to do with security, they just can’t stand that flash really is superior to the poor coding and slow framerates that jquery has caused.

      First of all I understand why Mozilla have taken these measures as clearly Adobe has been dragging it’s feet on keeping Flash safe but want to get on my soapbox.

      I love (or should I say loved) flash.

      I’m no computer expert, I’m a photographer, and my computing knowledge before I jumped into flash was how to do a for next loop in Basic from school computer lesions. Ten years ago I needed a website but wasn’t really clear how I wanted it designed but I then heard about Flash and it sounded perfect for my needs. Six weeks later, after about 2 to 3 hours a day and a couple of all-nights I had got to grips with flash and Actionscript and had the most beautiful website I could have dreamed of which took up virtually no system resource (as all the flash did was smoothly control transitions on and off the screen). However, I was aware and horrified by the ugly cumbersome over designed flash sites that were popping up, developed like that simply because they could be I presumed. And then everyone hates flash because ‘it takes up too much system resource’ (in the main). What’s the expression ‘killing your cash cow’! Of course it had it’s issues with security but so has everything to do with the web and like everything needs constant attention and improvement. It was propriety as well – but then so is Microsoft Windows, OSX, iOS, Javascrip etc – what’s the problem with that. In my, I guess limited, view, the real reason Flash died was because someone (mentioning no names) didn’t like the power adobe would have if it kept growing!! Just my view with limited knowledge but years of experience watching the computer industry f!$Qk us up the ar@s.
