Adobe Flash player is a vile spyware!
http://en.wikipedia.org/wiki/Zombie_cookie I just followed the advice and found several dozen files on my hard drive used by various sites to track me online. And this bypassing the browser safety mechanisms!
Even Firefox on Ubuntu is vulnerable
I wonder is ability to watch YouTube is worth having that Adobe crap in my system...
Also, they say M$ Silverlight and HTML5 are the same crap.
