Google’s Google Talk plug-in for audio and video calls is no longer needed, nor is the Google Earth plugin for looking at detailed satellite views on Google Maps. Other plug-ins have also become unnecessary as they’ve been folded into the browser. To alleviate the problem, we recommend enabling click-to-play for Flash rather than uninstalling it complete. On the other hand, Flash is still used for many different things - the videos on Facebook, for example, require having Flash installed. Other video-playback sites have also switched to Flash, and modern websites shouldn’t require it. Flash is becoming less necessary than ever, and you can now even view every single video on YouTube without having Flash installed. Flash: Flash is the plug-in you might still want.Head to the Java Control Panel and disable the Java plug-in if you can’t uninstall it. Even if you need Java installed (to play Minecraft, for example), you don’t need the browser plug-in enabled. Java: What more can we say about Java? Java applets have all but vanished from the consumer web - unless they’re being used for exploits - but the terribly insecure Java browser plug-in is still enabled by default.You’re doing them a favor by ditching it. Really, Microsoft wants the Silverlight browser plug-in to go away, too. So, if you still just have Silverlight installed for Netflix, you can go uninstall it now. If you’re one of them, there’s good news - in modern browsers, Netflix will just use HTML5 instead of Silverlight. Silverlight: Most people have Microsoft’s Silverlight plug-in installed for Netflix.But, at a certain point, we all uninstalled RealPlayer because it just wasn’t necessary. Plug-ins like Java and Silverlight have already hit that point for most people, and even Flash should get there one day soon. Even now, if you dug deep enough, you could probably find web pages that required you install RealPlayer to view their old videos. Plug-ins will likely never vanish completely from the web. RELATED: Why Browser Plug-Ins Are Going Away and What's Replacing Them A plug-in is a program that websites can require. They were necessary when browsers weren’t evolving fast enough - like back in the Internet Explorer 6 days - but now need to go away. An extension or add-on adds a new feature to your browser that you can use, if you like. Note that browser plug-ins are different from extensions, or add-ons. They aren’t sandboxed - except on Chrome, and even that sandbox won’t protect you from everything. If an attacker finds a hole in your browser plug-in, they can generally exploit that hole to gain access to the system. Chrome uses PPAPI, which is designed to provide additional sandboxing - but even it isn’t ideal. Internet Explorer uses ActiveX, which is notorious for its security problems. Firefox still uses the NPAPI plug-in system created for Netscape Navigator.
