      The article doesn't say you can't disable it. In fact, in the screenshot in the article, the disable button is clearly enabled.

      The last .NET update did the same thing, put in an extension to FireFox that you couldn't uninstall, only disable. Java does the same thing, I have TWO Java SE FireFox extensions disabled in my list (neither can be uninstalled).

      With this latest .NET update the uninstall button actually works for the .NET extension. At least on my Windows 7 machine.

      It says nowhere in the article that you can't disable it, just that you can't uninstall it.

      In fact, the screenshot in the article shows an active disable button, but not an active uninstall button.

      In a previous post, someone said that this is due to admin privileges issues. Most extensions are installed by a user and reside in a user-accessible directory. Firefox allows for system-wide installation of extensions by pointing to them with a registry entry. System-wide-installed extensions fundamentally can't be uninstalled directly by a user without some sort of privilege escalation, which Firefox doesn't support. MS didn't explicitly disable uninstallation, it's just a side effect of being a system-wide installation.

    ClickOnce makes it possible to install applications over the web (WoWAceUpdater was an example of this) at the user's demand, it will not automagically download .NET-capable trojans to send back personal information. If you're truly paranoid and wish to disable it, the instructions are pretty simple and can be found by googling.

  9. It's a string in the user-agent by tepples · · Score: 5, Informative

    Adds ClickOnce support and the ability to report installed .NET framework versions to the web server.

    I do not like the sound of that nor does Annoyances.org as the article notes. I don't like the idea of sending anything about software on my computer to a web server without me knowing about it.

    But do you know what your browser is already sending? Mine is sending this:

    "Windows NT 5.1" is Windows XP, and "Gecko" is the HTML/CSS engine used by Firefox, Iceweasel, SeaMonkey, Fennec, etc. Sites can query the versions of various addons that handle an object type, such as Java SE and Flash Player, by embedding such an object. What's so different between querying the .NET Framework version through this add-on and doing so through the Silverlight addon?

    In my system I also have the "Java Quick Starter" (from Sun), and I already removed the Skype add-on.

    As a Firefox extension developer, I've received several complaints about disappearing toolbar buttons, and the answer is always the same: check for the Skype extension that was installed without your consent, and uninstall it. Plus, navigating the browser history was a lot slower, and removing that add-on solved the problem (the Skype extension will scan the page contents to substitute phone numbers by Skype actions).

    This is not limited to Firefox, as this stuff has been happening in Internet Explorer for a long, long time. Still, it would be nice if Firefox would protect its users from non-authorized extensions, warning of what was installed, and providing a easy way to uninstall/disable it.

    Apparently, MS released a v1.1 of the plugin, but it can't install if you left 1.0 disabled (like I did). If you re-enable the plugin, then go manually re-download and re-install the hotfix which included this plugin more recently, you will get v1.1 of the plugin, after which, you CAN uninstall it.
    Note that disabling the plugin still leaves a string in your user-agent saying what version of .net you have installed, so either get it uninstalled, or go check and delete the right entry from general.useragent.extra.* in about:config

    They aren't 'stealth'ing in an add or nor are they 'disabling' the uninstall button.

    The 'uninstall' button is for user specific addons, not system wide add ons. The uninstall button has never worked for system wide addon installations. It is a feature, and a required one if you expect Firefox to actually get anywhere in the business world. This is done by adding a single registry key and can be done for ANY add on, regardless of who makes it or where it is installed.

    It serves two purposes. First it allows things to install add ons before the browser is installed so that when you later install Firefox it will be aware of existing items and not require you to jump through hoops to get them to work. Second, it allows administrators and other software packages to install something globally, for all users of the host, without requiring each user to manually install the add on and keep it updated.

    I'm sorry that this doesn't fall into your narrow little view of the world, but for the rest of us this sort of thing is a requirement to use Firefox in the business world.

    Finally, there is a very simple solution. Don't install software that does things you don't want it to do. You're an idiot if you think there is anything what so ever that Firefox can do to stop this sort of thing. There isn't. Add ons will ALWAYS be able to install themselves with out notifying you, welcome to open source, EVERYONE can see how to do it, thats a feature of open source. There is nothing Mozilla can do to stop it short of releasing a version with some non-OSS component that can be used to prevent it from happening using digital sigs to verify that only allowed add ons are installed or not load them. And as soon as they do that Slashdot will be ranting and raving about freedom to do whatever the hell it wants.

    You got your software freedom, you wanted everyone else to have the same access to the software as you do. Great, they do, now you get to deal with the consequences of that.

    Its not like user add-ons can't do the EXACT SAME THING. All you need to do is remove write permissions from your own files when you startup and Firefox won't do shit when you tell it to uninstall it except throw an error. Any add on can do that, and Firefox is unlikely to ever 'fix' that problem as its one that Firefox shouldn't be responsible for.

    You can fix the problem on your computer yourself to make sure this doesn't happen with some registry permissions in HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla, take away all write/modify access to this key from everyone after you've installed Firefox. Problem solved. That is where various addons for Mozilla software can be installed globally by a system administrator.

    As for Firefox removing that feature, go ahead and let that happen. Find out how many IT departments suddenly want even less to do with Firefox. I'm sure they'll love you for having it removed when they have to do something retarded like run a login script to roll out extensions rather than just pushing a registry change via group policy.

    The worst part is that this gets modded insightful. This isn't fucking insightful, its ignorant, short sided and shows a complete lack of understanding about whats going on and why.

    Whats worse is ignorant dipshit comments like this end up making me fucking defend Microsoft.

    Get a clue, then start bashing, people with far more intelligence and understanding of this sort of thing work on it, not you, ever consider there MAY be a reason?

    When you disable the extension Firefox does not load anything other than its manifest. It doesn't matter WHAT the extension does or how 'deeply the extension hooks into the OS', its not loaded. Your lockups are unrelated to this extension if you have it disabled. The could very well be related to any number of other things that change during patching, but this particular extension is not it.

    Remember, they had UNIX license directly from AT&T too and selling it as Xenix. It really looks like they try to code Unix again in a different sense but fail, over and over. Judging from OS X Office releases, they wouldn't be a bad Unix/NeXT coding company either.

Because, if the submitter, or the editor, or anyone had bothered to do so, they'd realize what a total non-issue this is: It's already fixed, which is why it works fine for you, drinkypoo.

    This blog states that the plugin was initially installed as a system-wide thing. And, with FF, users can't simply remove system-wide things by themselves. Which, of course, makes sense to anyone who has spent more than ten minutes working on a system with proper basic security. They detail a long-winded workaround.

    Right. So. Then there's this:

    Update (5/2009): We just release an update to .NET Framework 3.5 SP1 that makes the firefox plug in a per-user component. This makes uninstall a LOT cleaner.. none of the steps below are required once this update is installed.

    I'd guess that you simply already have this newer version of the .NET package, which includes a Firefox plugin which is installed in a manner more in-keeping with what folks might normally expect, and accordingly can be uninstalled in a manner that folks might normally expect.
