Firefox Disables Microsoft .NET Addon

ZosX writes "Around 11:45 PM Friday night, I was prompted by Firefox that it had disabled the addons that Microsoft has been including with .NET — specifically, the .NET Framework Assistant and the Windows Presentation Foundation. The popup announcing this said that the 'following addons have been known to cause stability or security issues with Firefox.' Thanks, Mozilla team, for hitting the kill switch and hopefully this will get Microsoft to release a patch sooner." Here's the Mozilla security blog entry announcing the block, which Mozilla implemented via its blocklisting mechanism.

    Microsoft has deservedly taken a LOT of sh*t for forcing this addon into Firefox unannounced - AND preventing you from disabling or uninstalling it - unless you yank it out of the registry. It's nice to see the Mozilla folks say "NOPE, you...'re NOT doing this to our browser, now get lost"

      The .NET installer/updater that forces this addon into Firefox is running as administrator or even system rights. How should a non-running app protect itself against a code injection in their home directory done by a process with system privileges? Without creating another mess of cryptographic signing, super-super user and files undeletable when Joe Sixpack decides to uninstall?

      I'm sure the Firefox team is working on hardening their application against scummy plugins that disallow being uninstalled, but I fear it's not exactly trivial protecting against administrator privileged malware without breaking a whole lot of other stuff.

  2. The real reason why they want to hack user agent by Ilgaz · · Score: 4, Insightful

    While some slashdotters think otherwise, Java/Windows install base is huge thanks to couple of very popular apps and tiny games. Since companies these days looks for multi platform, multi arch; MS needed to show that their herd has been installed/infected by .NET too.

    So, they haxor the user agent to show that clueless CTO that their 90% of users have .NET so they should use it instead of massively multi platform Java.

    Anyway, as you see, karma is a real bitch and if Sun had a real management, they could milk this issue but... Lucky for MS, Sun is under auto pilot, even under Larry Ellison's Oracle.

      If Mozilla had been installing Firefox without the users' consent and prevented the same users from uninstalling it, then yes, Microsoft would have been justified to hit the kill switch.

    So your argument against people switching away from MS, is that people use MS??
    That's the classical excuse of to beta human: I can't do it, because nobody does it.
    And why does "nobody" do it? Because everybody uses that "argument" to not do it!

    The best thing is, that it isn't even remotely true that nobody does it. You're reading a comment from someone doing it right now. But it's so convenient to ignore it that, isn't it?
    Maybe that's the difference between alphas and betas. Alphas have no problem being the first in the club, to start dancing. No they even grab a girl and make a show out of it! ^^ (Because they know that that makes them the leader. Something that is very handy and feels great. Killing any insecurity-based awkwardness.)

    So if one person can do it, then two can too. Including handling MS file formats. Including the ability to be in a MS (SMB) network. And so on.
    So if two can do it, everybody can.

    Which means nobody needs to use MS software. But they want it! Why? Because it's less effort. One can be lazy. And the excuses "always work", to lie even to oneself, about wanting to switch.
    "Oh, if only others would use it! Then I would too! But in this situation? No way!" Except that you wouldn't. Or if you would, then I wonder what a pathetic kind of cattle you are, for always trying to conform, even if it's not what you like.

    Hell, I'd even prefer to hear that you actually prefer Windows, and that this is mostly because you don't like all the work required to switch. That would at least be honest. And while not agreeing with the view, I could absolutely comprehend and accept it.

    Do yourself a favor, stop imitating others just to be "accepted", stop caring what others think of you, build your own set of values, be you, do what you like, and strongly stand behind your reality. That is a basic human right of everybody. And we will not hate you for it. No, we will love you for it. (Isn't it strange, how doing the opposite of what you did, will give you what you always wanted? ^^)

    While I was angry at Microsofts silent installation of this component in Firefox and there is part of me that is ready to cheer on Mozilla for disabling it, I also feel disappointed by the reaction to this.

    Not only are they vulnerable versions of Microsoft's add-on disabled, but also all versions indiscriminately, including the patched version that Microsoft rolled out last this Tuesday. Just as some people may have been impacted by Microsoft's original silent installation, how does Mozilla know whether an end user actually uses sites that depend on that add-on or not?

    Imagine what would have happened if Mozilla remotely disabled everyone's Flash plug-in each time a new vulnerability was discovered in it? There have been 0-day exploits in the wild for Flash and just think about it's install base. Or the Adobe Reader plug-in? Lord knows it's a more deserving candidate given its history.

    In this case there may be some justification in that the unrequested component might pose yet unknown risks, but now I have to wonder what Microsoft's strategy will be during their next update cycle - to re-enable it given that they've fixed the hole in question? Did Mozilla just give Microsoft precedent that would support it disabling Chrome Frame in future?

    As a customer of both parties I feel that I've been dragged into someone else's war, which is being waged with my computer as the battle field.

    And, yes, by all rights, Firefox should support .Net natively. It already has special support built in for Java, so there's no reason why it shouldn't include the same hooks for .Net other than an irrational hatred of Microsoft.

    Try again anonymous Microsoft fanboi.

    As far as I can see there is nothing special special in Firefox for Java to function unless you are referring to the standard plugin architecture that Firefox/Mozilla provides for all plugins.

    Java is installed at the choice of the user where the .NET plugin is installed by a Windows update without informing the user. Once installed the Java plugin can easily be removed by the user via the Firefox configuration GUI but the .NET plugin can not be installed without doing some complicated registry and configuration hacks.

    To me this looks like an attempt to drag Firefox down to the level of IE by silently adding .NET holes into Firefox and then they can say, "It's not us because Firefox has the same problems we do".

  16. Google is NOT competing for browser share by SmallFurryCreature · · Score: 5, Insightful

    People, please let this idea die VERY quickly. Chrome is NOT there to get an install base for Chrome. It is there to get an install base for modern browsers with fast javascript/DOM.

    Googles operates in the browser and in order to be able to get the next generation products out there, it needs to ensure that those products can be run. IE/MS ain't capable of this, so they both push MS by making them scared to completly loose the browser AND by capabilities to IE to make it play catch up with the real browsers.

    In a way, what Google is doing is installing electricity cabling into every house. NOT because it wants to be in the utility business but because it has all these design for electric machines and they ain't going to be selling them to people who use candles and woodstoves.

    MS on the other hand does NOT want people to have modern browsers, or rather not browsers that act like browsers. Its business relies on activex and .net and the like to keep apps closely tied to their windows OS.

    MS fears projects like gmail and worse wave. It knows that its software is increasingly a major cost of computers (check it, hardware prices go down, MS prices go up) and while so far its software offers a lot more features, the sign of netbooks is that, a lot of them ain't needed. I got a netbook (with linux) that is not nearly as capable as a full PC. I can't game on it, its office tools are simplistic but guess what, it is all I really need.

    MS has been selling XP, a lot, for netbooks but it has been doing it at a fraction of the price it would like to charge and really, it only sold XP so cheaply because else Linux would have been installed. You would be right in assuming a LOT of people would replace Linux with an OLD XP copy (license of an old PC you threw away is still valid) but MS doesn't even want the idea that there maybe yet another OS out there. An OS that while not perfect is good enough. People are already getting dangerously exposed to this idea by their cellphones. Quick poll, who has Windows Mobile and is willing to admit it? Everyone knows that an iPhone gets you the girls, this even goes for girls.

    MS ideally wants to sell you their OS for 300+ dollars, that doesn't fit well for a 300- netbook or indeed a mobile phone, but that is MS business model, and ideally, you should spend another 300 for the office suit. (please, MS fanboys, do NOT link to student discounts or OEM versions. Full price for the box in the MS store.)

    Google is doing something completly different. It is saying. Nah, you don't need a 300 dollar OS with a 300 dollar productivity suite. Just a browser (free) on free/cheap OS and you got all you really need. For free. Sure, there are some angles (your data is on the google servers) but for a lot of people, it is good enough.

    AND that, is what scares MS. Because... even if people would still use windows, the window sthey would be using is their old XP. This is already the case in a many companies. And without the cashcows of Windows/Office, how can MS afford all its other attempts to control markets?

    The browser wars are back, but they are being fought for a different reason. Chrome is NOT netscape 2.0

    Doesn't it seem a little odd that the company that is competing for market shares in the web browser area would create a addon for a competing company?

    Not really if you look at where the real competition is occurring.

    The REAL product that Microsoft is trying to protect is the Windows platform. This is how Microsoft maintains their monopoly. IE is merely a means to try to control the web market to use Windows only across the board. The windows platform maintains much of its monopoly power by controlling the software to run on only Windows. Microsoft has long known that 3rd party developers were a big factor in building their monopoly, and keeping them on Windows maintains that monopoly.

    This plugin lets you run parts of .Net on Firefox, correct? .Net is largely Windows only software, correct? So by having Firefox (an increasingly popular web browser on Windows) run .Net software, Microsoft is trying to maintain .Net on web browsers as a viable platform. By doing this they try to ensure that you'll need a Windows computer to run .Net software on a browser. The alternative is that Web developers increasingly reject .Net components because of the increasing popularity of FireFox (and .Net not running on FireFox, thus developers don't want to lose the market share and choose non .Net alternatives). That's bad for Microsoft, since it means more inter-operability with other OS's, which would decrease the relevance of Windows.

    Pretty clever, really. Frankly I think the Firefox developers should stop this nonsense not only because of the security concerns, but mainly because it's an attempt to control Firefox by Microsoft. Does Mozilla really want to answer to whatever Microsoft decides to inject into Firefox this week?

    I also think it's a anti-competitive move by Microsoft and an abuse of their monopoly power. I doubt anyone will do anything about it though.

    No, actually, it is not. Not at all a good thing, quite the opposite. If you are using firefox to run "content" via a closed, windows-only system like .net, you might as well be using IE. In fact that would be better - at least no one would be fooled into thinking they were writing something that would work on firefox when in fact it would only work on Windows/Firefox.

    There is a lot of interesting comment there, including the fact that while everyone is crying about Microsoft "secretly" adding the plugin and preventing users from disabling it, Mozilla doesn't even give users an option to enable it! Their blocklist is all or nothing. Why doesn't that bother anyone here?

    Because MS forced the plugin out without user consent and without even a disable option to begin with. Either of which is sufficient in and of itself to classify this bug as malware and remove it whenever encountered without further fuss.

    Taking this kind of control away from the users is simply unacceptable, doubly so for businesses.
