Microsoft Update Quietly Installs Firefox Extension

A routine security update for a Microsoft Windows component installed on tens of millions of computers has quietly installed an extra add-on for an untold number of users surfing the Web with Mozilla's Firefox Web browser.

Earlier this year, Microsoft shipped a bundle of updates known as a "service pack" for a programming platform called the Microsoft .NET Framework, which Microsoft and plenty of third-party developers use to run a variety of interactive programs on Windows.

< snip >

Having earlier checked to see whether the service pack had caused any widespread problems or interfered with third-party programs -- and not finding any that warranted waving readers away from this update -- I told readers not to worry and to go ahead and install it.

I'm here to report a small side effect from installing this service pack that I was not aware of until just a few days ago: Apparently, the .NET update automatically installs its own Firefox add-on that is difficult -- if not dangerous -- to remove, once installed.

Annoyances.org, which lists various aspects of Windows that are, well, annoying, says "this update adds to Firefox one of the most dangerous vulnerabilities present in all versions of Internet Explorer: the ability for Web sites to easily and quietly install software on your PC."

< snip >

The trouble is, Microsoft has disabled the "uninstall" button on the extension. What's more, Microsoft tells us that the only way to get rid of this thing is to modify the Windows registry, an exercise that -- if done imprecisely -- can cause Windows systems to fail to boot up.

I switched to Safari

Me, too, and it is much faster but I have some firefox extensions that I need, and after running awhile Safari seems to hog resources (worse than firefox) and conflict with my graphics program so I'm back to the stable firefox 3 release. I've tried the beta too and will switch when my add-ons are updated.

Haven't tried chrome. Seems like it won't do what firefox does either even if it is fast. Building browsers without add-on capability (just about any program, actually) seem very dumb and limiting IMO.

Darn! I don’t even have it!

Can I still wail and gnash my teeth in false indignation?

Bump for later. How do we turn it off? (plain English please)

[antiRepublicrat]

Firefox extensions can be manually removed. Googling “firefox manually remove add-on” or “extension” will get you tons of how-tos.

Sometimes those people really piss me off.

Firefox extensions can be manually removed.

Yes they can, bu this article explains that with this particular extension, it requires registry editing.

Not a good thing.

I turned of automatic update after it crashed this Vista, last Jan.
I also have had a problem with, Firefox....could be connected, I suppose.

I’ve had trouble with Firefox freezing for a few seconds at a time while pages are loading and now I wonder if these two things are connected?

Same problem, but on both Linux and Windows machines so I suspect not.

I turned off my automatic update after last year on April 14, when that a Windows update on one of our computers interrupted the functioning of our tax preparation software. (we are a CPA firm). Intuit fixed the problem on the computer, and subsequently let us know that the update was also reported to be interfering with Quickbooks. The timing of the

Smart. As an ex IT person(retired)I have never enabled automatic updates. I always make it ask me what I want to install. I recently had problems with SP3 for XP. It works ok on my roll your own computer but causes no end of problems on my Dell. I understand from some other Dell owners that it has caused problems with their machines also. Bottom line: Don't trust updates!

Not only that, but if you are using windows(which I assume you are) and you use Netflix instant viewing capability, Netflix doesn't recognize Safari except on Apple machines. Won't allow you to watch movies on Safari if you are using windows, so I went back(actually never really left)to Firefox, which I have never had any problems with.

There, fixed it for you. :)

Click “Tools” and then “Add-ons”. It’s there listed as “Microsoft .NET Framework Assistant” and it’s version 1.0. There is a disable button. Click it, and restart the browser. Now it’s disabled.

Google Chrome hogs resources too. I used it for about a month and I never noticed it was any faster than any of the other browsers I’ve used.

Thanks. I found it. It's in the "Extension" tab and have disabled it.

I just checked on this PC and noticed there are no Windows extensions. Then I realized it's Linux Mint. D'oh!
