For years, Adobe Flash Player has been one of the most popular plug-ins used by web browsers to reproduce videos, web ads, and interactive animations. But now its position is rocked by some security concerns and safer alternative solutions.
 
Contain the built-in version of Flash running in the sandboxed mode. This method is safer than running Flash as a plugin. What about Safari, it disables? Flash Player by default starting from macOS Sierra. HTML is the newer and safer way of browsing the web. But it does not contain any security issues.
 
However, the reality is that you still may need the  Flash Player on your device. Many websites will not work if you uninstall it completely. Live streams like BT Sport can only be delivered in Flash, so if you are the BT Sport customer, you'll want to keep the Flash Player. In addition, a great number of gaming and education sites use Flash and until they implement the HTML5 standards, you'll need the Flash Player.
