Most people don’t know it but Adobe does have some settings you can change for Flash. If you like to tinker with settings you can do so here. There are some security settings that may be useful in keeping tracking or malware away. Basically you can set rights to sites globally and also white-list some sites that you like (and trust).
It is done through a web page at: Flash Player Control Panel
The setting pages looks like a graphic but it actually works. As always be careful when changing any settings.
