Forget the flash downloads. Go get Chrome as that has it built in.
"Google has been bundling Flash with its Chrome browser for more than two years, - See more at: http://www.computerworld.com/s/article/9233695/Google_sandboxes_Flash_in_Chrome_for_OS_X#sthash.9Mu1k4Rm.dpuf"
i have had trouble with flash player before 3 months ago. couldn't see videos but could hear them. eventually, i got it, don't know how, but i uninstalled and reinstalled at least 1/2 dozen times. now, this week, i can't watch nor hear any fb videos. i haven't gone to youtube to see if i can't watch there, but i'm a fb/email kind of mac user mostly. any of you had these issues and have suggestions? consider me a basic person, incapable of anything complicated.
