The browser that supports the java plugin. Instructions: use a second browser for Java, Flash and plugins. Java plugin does not appear in add-ons management window

Some versions, apparently by mistake, Google chrome, do not support Java, from which the question arises, how to enable Java in Chrome?

Why do this? - Yes, everything is simple, a man in the street wants to enter the network and watch some videos, or play a game, but he cannot do this, and that's all because Java is not connected. This phenomenon is common in older Chrome versions.

It is not difficult to do this, you do not have to install the browser again. Below are the solutions to this problem.

1. Why Java is missing from Chrome

In 2015, Google dropped support in nPAPI browsers... This architecture, which is used by many plugins, and essentially all Java.

Therefore, most of the videos or games do not work for google version Chrome is over 15 years old.
But there is a way out, and it consists in turning on the disabled support for NAPI in GH. And it's not difficult to do this.

2. How to enable Java in Chrome

Several steps to solve this problem:
1. Launch the browser. Further actions we produce it in a running browser on a PC.

3. Now a new item will open, it is associated with NPAPI... Below the item is marked with a red line. Most often it looks like this, but there are other variations.

That's all, Java should now work in the browser.
Since NPAPI is located in the "experimental" features section, it is activated at the user's own risk. In general, on the inclusion page itself there is a sub-clause about this.

3. Enabling does not help

The reasons for this:
- required plugin does not function;
- there is no plugin in general;
- Java version requires updating.

That's all possible reasons, other problems were not encountered by users, except that such a reason may be a problem with the characteristics of the PC. Well, or viruses prevent you from functioning fully. Scan the system and remove unwanted software.
