Ok, let's tackle Adobe Flash.
Try uninstalling then reinstalling a new copy of the plugin.
Uninstall Flash
Install Flash
I know you already repaired permissions but you need to do it again after reinstalling the Flash plugin.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. *Quit Disk Utility and restart your Mac.*
