Some versions, apparently by mistake, Google chrome, do not support Java, which raises the question of 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 over a new one. Below are the solutions to this problem.

1. Why Java is missing from Chrome

In 2015, Google dropped support for 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.
2. In the line “ Url", Enter the following value: chrome: // flags / # enable-npapi, right in the place of the address bar.

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. Turning on does not help

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

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 fully functioning. Scan the system and remove unwanted software.

Plugin disabled

Let's work out how to see whether the plugin is enabled or not. Go to the "Extensions" section in chrome.
This is done through the settings, or the address bar, in which you will need to enter: chrome: // plugins /.

If everything is working properly, try putting a tick in the "Always run" checkbox. Thus, the plugin will function immediately upon launching the browser.

Download Java plugin

Java can be downloaded from its official website - java.com. The site, in theory, will independently translate the page into the desired (Russian language)
Go to the "Download Java" section on the website and start downloading.

After downloading, install the plugin. The whole installation takes place in automatic mode... After it finishes, restart your computer and enter the browser. Everything.

Java is mainly used for online games... To start correctly, you need to install it correctly and update it from time to time. It should also be remembered that Java is a programming language.

To install it, simply visit the developer's site and download (java.com). There we confirm the user agreement and download. By the way, it's completely free, you don't have to pay for downloading and there are no hidden fees.

After downloading the application to your computer, close the smear and other browsers you are using. Only after closing all browsers, start installing the application.

Update

After downloading and Java installations install it automatic update... The program itself will check for updates and notify you about it. You can change the update settings in the Update tab in the control panel.

There you can also check for updates manually, but it is more convenient, of course, to allow the program itself to do this. Do not forget to delete old versions of Java application after updating - this will help save space on your hard disk and eliminate possible threats to the security of your personal computer.

How to check the functionality of this application

Everything is very simple, to check it just go to the testing pages:

It will not take more than ten minutes of your time, but you will find out if this program works for you.

Correct inclusion of this application

Enabling Java does not present any problems. Just follow the instructions and you will succeed:

Troubleshoot application problems

There are several reasons why a plug-in program may stop working. Let's consider the most basic ones:

Removing Java plugin

Choose your operating system and strictly follow the directions.

1. In the "Start" select "Control Panel".
2. Find the "Remove Programs" tab.
3. We select the program and click "Delete" and confirm our action.

1. Open "Start" as standard.

Many Internet users are often faced with the fact that the drop-down menu does not work on the sites, videos do not play, nothing happens when buttons are pressed, etc. Or, for example, pictures are not shown, but instead the inscription appears: “This plugin contains security vulnerabilities. Click here to enable the Java (TM) Platform SE 7 U Plugin. " All this is due to the work of the Java plugin, which is present in browsers.

In some browsers Java is preinstalled, in some it has to be downloaded separately. But even if this plugin is installed in your browser, it is not a guarantee that it will work, because sometimes the Java plugin needs to be enabled.

If you encounter any problems displaying web pages, check do you have Java plugin enabled... To make it easier for you to do this, I wrote a small script that checks the browser and displays the appropriate inscription. Here is the analysis result for your browser:
