While running OSX 10.8.2, Safari 6.0.2 with Flash 11.5.502.110 I attempt to use hulu or amazon prime and I get a "blocked plug-in" error which sends me to Adobe for a flash download. I have reset safari, uninstalled flash, reinstalled, etc. to no avial. Any suggestions?
Take each of the following steps that you haven't already tried.
1. Select Safari ▹ Preferences ▹ Extensions from the Safari menu bar. If any extensions are installed, disable them and test.
2. In the Safari preference window, select Privacy ▹ Remove All Website Data. Close the window. Then select ▹ System Preferences ▹ Flash Player▹ Advanced and click Delete All. Close the preference pane. Test.
Triple-click the line below to select it: /Library/Internet Plug-Ins Right-click or control-click the highlighted line and select Services ▹ Open from the contextual menu. A Finder window should open. Is it there more than one Flash plugin in the folder? Is there another folder named "Plug-Ins (Disabled)" alongside it?
