In Firefox I discovered that under Preferences/Search/SearchItDown can't be removed. I was able to remove it in Safari. SearchItDown is preventing my MAC from shutting down using Apple / Shutdown. I have to now use the button. Also some programs that are open can't be closed unless I use fore quit. I'm on a MACbook Pro using Sierra 10.12.3

Flash: Grab the uninstaller from here: Uninstall Flash Player | Windows Uninstall Flash Player | Mac

Then reinstall the latest version.

Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.
