It's been down for at least 6 months.I've uninstalled and reinstalled Safari and Flash but nothing has worked. I've already emptied my cache and deleted all extensions. Java is enabled. There is no Adobe Flash folder in the Adobe Application folder though. I can't find instructions on how to fix this.
I feel like I'm going crazy and I want to throw my computer out of the window...Or just switch permanently to Firefox. I have all of my passwords saved in Safari so I'd rather not do that though. Please help!
Finally figured out solution to same problem on MacBookPro running 10.8.
Safari>Preferences>Security> check 'Enable plug-ins' on.
Flash now working.
