I've been meaning to write something up about Flash cookies for awhile now, but I just found this article that sums the problem nicely:
John Graham-Cumming: What's wrong with Flash Cookies?
I hate Flash. As far as I'm concerned, it's too buggy, it's too crashy, and it hides too much of what it is doing from the user. It's mainly used by advertisements anyway. I'll be very glad when HTML5 is at the point where it can wipe Flash off the face of the planet. Flash for me is similar in many respects to the old ActiveX and Java applets we had to endure in the late 90s early 2000s.
When I install a browser, one of the first plugins I install is Flashblock:
Flashblock for Firefox Flashblock for Chrome
Flash lets ME decide when I want Flash. If Flash is on a page, it just shows a "play" button, so I can just hit play if I want to see the Flash. Usually, I don't, and it helps my browsers run faster and makes them more stable. Soon, we'll be free of Flash forever (I hope).
