Although browser games continue to be a popular format for game development, the technology behind browser games has changed rapidly in recent years. As early as 2013, Chrome announced that it would no longer support Netscape Plug-in API (NPAPI) due to concerns about browser security, speed and stability. Support for NPAPI plug-ins has been discontinued with version 45 of Chrome, which was released on September 1 of last year. Microsoft’s new Edge browser also does not support these plugins, and Mozilla recently announced that it will also remove plugins (except Flash) by the end of 2016.
Since Unity’s web player uses NPAPI technology to work in browsers, all Unity games will no longer load when they are opened in Chrome.
This was a concern for developers who rely on Unity to work in browsers to preserve themselves. As you read this, you probably already have a Unity game on the web, or you’re considering launching one, but you’re not sure if the traffic for your studio is there. Unity’s solution to this problem is Unity 5, which includes an option to export games to a WebGL format without a plugin. It was in preview mode until its full release in Unity 5.3 on December 8, 2015, and we are starting to see more and more games downloaded in parishes using WebGL builds. Some games had very few problems with the new export, while others encountered major problems due to the platform’s limitations. WebGL export is still under development because performance is improved and vulnerabilities are being developed, but it is a long way.
What is the Unity Web Player?
Some online games use the Unity Web Player. When you launch a game for the first time, you will be prompted to install the Unity Web Player plugin if it has not already been installed.
Play with Google Chrome? Since the Unity Web Player is already installed in Google Chrome, you will be prompted to run the Unity Player permission on the site.

The Unity Web Player is depreciated.
From 2019, most browsers will no longer support Unity Web Player. These browsers include Google Chrome, Firefox, etc. Over time, many browsers have begun to neglect support for NPAPI plugins, including Unity 3D Web Player and Java.
NPAPI (Netscape Plugin Application Programming Interface) is an API for developing browser extensions and was first published for Netscape browsers in 1995. As HTML5 becomes more popular and supported with new browser versions, plugins that use NPAPI are gradually being removed.
Instead, Unity itself has asked developers to switch to WebGL (Web Graphics Library), which is a JavaScript API used to render 3D and 2D graphics in any specified browser without the use of plug-ins. This is the modern version of belt processing and has gained a lot of traction over the years due to its simplicity and efficiency.
The problem with converting to WebGL is that it is not as easy as pressing a button. WebGL has more limitations than Webplayer, so some things in WebGL need to be done differently (especially the economy…which still has some problems in Unity.) Some developers may not have the bandwidth to port their games to WebGL.
How can I operate the Unity Web Player?
Even if the Unity Web Player is officially disabled and there are no options to enable it in the modern browser, there are still some alternatives you can do to make the web player operational. Below, we have listed some of the methods you can use, but be aware that there is no guarantee that everything will go well (this is obvious because there is no official support).
