From PC Mag.com:
In recent months, browser makers have slowly been showing plugins the door. Chrome is pausing non-essential Flash content, for example, and Microsoft Edge is giving plugins the cold shoulder entirely. Now it's time for Mozilla to say goodbye.
It will be a long farewell, though. Mozilla plans to end support for aging plugins, but not until the end of 2016.
Specifically, Mozilla will ditch the Netscape (yes, Netscape) Plugin Application Programming Interface (NPAPI) on Firefox. At one time, NPAPI was essential to the Web experience, but "streaming video, advanced graphics, and gaming features have all become native Web APIs in the past few years," Benjamin Smedberg, manager of Firefox quality engineering, wrote in a blog post.
"As browsers and the Web have grown, NPAPI has shown its age," he wrote. "Plugins are a source of performance problems, crashes, and security incidents for Web users."
As a result, Firefox will no longer support "most NPAPI plugins" by the end of next year, Smedberg said. "Firefox began this process several years ago with manual plugin activation, allowing users to activate plugins only when they were necessary."
There is an exception to the rule, though: Flash.
"Because Adobe Flash is still a common part of the Web experience for most users, we will continue to support Flash within Firefox as an exception to the general plugin policy," Smedberg said. "Mozilla and Adobe will continue to collaborate to bring improvements to the Flash experience on Firefox, including on stability and performance, features and security architecture."
This also means Unity Web Player-based content will operate directly in the browser, without plugins. "Unity is diverting resources into alternative Web technologies and will begin the end-of-life process for the Unity Web Player plugin," the company announced last week.//Related Articles
The game engine no longer recommends the use of its Web Player; Unity 5.4, expected in March 2016, will not ship with Web Player support. Users will instead be directed to the company's WebGL export, which uses standard APIs.
Mozilla also suggested that websites and publishers using plugins like Silverlight or Java "accelerate their transition to Web technologies."
"The Web platform is powerful and can usually do everything that a plugin can do," Smedberg said.
