Adobe Flash update keeps coming up. Why?
I am using Yosemite. Every time I go to certain sites, I am told I need to download and upgrade Adobe Flash in order to view the site. It won't even let me say no, so after downloading and updating many times, I now close out Safari and reopen it so that I won't get the message. What is going on?
iMac, Mac OS X (10.6.1)
