Browser plug-ins are one of the largest security vulnerabilities facing today's computers, and Google aims to remove this issue from their Chrome browser once and for all. Starting in January 2014, Google will begin banning all of the most widely used browser plug-ins and will insist that developers begin using programming methods that use standards built directly into the web.
Most of the plug-ins featured on Chrome use the Netscape Plug-In Application programming interface, a technology that was state-of-the-art more than 10 years ago. Plug-ins should not be confused with much safer Add-Ons, which Google distributes through its Chrome Web Store. Fortunately, plug-ins such as Microsoft's Silverlight, Unity, Java, Flash, and Facebook Video will be white listed in the ban, so most of your services should continue functioning normally.
