Not exactly breaking news but better late than never. Prevent your favourite browser from becoming Internet Fire Explorer Fox.
2nd link has lots of screen shots and may be easier to follow.
This update adds to Firefox one of the most dangerous vulnerabilities present in all versions of Internet Explorer: the ability for websites to easily and quietly install software on your PC. Since this design flaw is one of the reasons you may’ve originally chosen to abandon IE in favor of a safer browser like Firefox, you may wish to remove this extension with all due haste.
I like Microsoft products overall, but I cannot and will never condone blatant misuse of corporate power to distribute useless, unasked-for software to masses who do not have the skills to tell part good from bad or how to handle issues like the above.
The Assistant, if at all, should be an optional package, with clear user consent granted before any installation. Furthermore, the installation should be fully 100% revocable, so that anyone using the computer can do it, via the standard Add/Remove panel.
This is a very serious breach of user trust. Not only is this package delivered without explicit approval, it’s also made difficult to remove. Moreover, its use is not clear. Lastly, the change affects third-party software, not one of Microsoft products, so the question is, what the hell did Microsoft want to achieve with this nebulous, spyware-like update? Animosity from a few trusted users? Force people not to install updates or use older versions of their products?
