Simply ... they do things to you without your permission! That just sux! (Electronic rape if you will )Remember that.NET Framework Assistant add-on that sneaked into Firefox without explicit permission from end users?
Well, the code in that add-on has a serious code execution vulnerability that exposes Firefox users to the “browse and you’re owned” attacks that are typically used in drive-by malware downloads.
What did they do...
Well if you have Firefox installed you sometime enhance it with add-ons.
All well and good. That's your (or my) choice!
But!!!!! M$ decided that Firefox 'needed' a .Net add-on and installed it WITHOUT giving you a choice.
Then that non-optional piece of crud software has a freakin security hole!!! Arrrrr!!!!
I blinkin well use Firefox to avoid security issues!!!!!
Repeat after me ... DON'T TRUST !!!
