I am using IE8, and have Flash turned off by default (I enable it for specific sites that need it). When I was visiting a Stack Exchange site, I noticed that on all pages I get the request to run Flash. I can't see any need for Flash on the majority of pages.
Is this a data collection effort (Flash cookies?) or for something else?
I want to know so I can turn it on (if needed) or off to improve perf.
