How to Enable Java in Chrome

Modern versions of Google Chrome no longer support Java plugins by default due to security concerns. However, if you need to run older web applications that rely on Java, there are several alternative methods to enable Java content in Chrome. In this guide, we’ll explore these options and how to set them up effectively.

Why Doesn’t Chrome Support Java?

Since version 45, Google Chrome stopped supporting NPAPI plugins, which were essential for technologies like Java and Silverlight. This decision was made to enhance security, as NPAPI plugins were prone to vulnerabilities that could be exploited by hackers. Now, alternative methods are required to execute Java code.

Methods for Running Java in Chrome

1. Use Internet Explorer or Firefox ESR

If you need to access Java content, the simplest way is to use an alternative browser. Some older versions of Internet Explorer and Firefox ESR (Extended Support Release) still support Java plugins.

  • Internet Explorer: Open the site in IE, which has direct Java support.
  • Firefox ESR: Download and install Firefox ESR, which still supports NPAPI plugins.

2. Use the IE Tab Extension in Chrome

The IE Tab extension allows you to open pages in an Internet Explorer emulator within Chrome, enabling the use of Java and other legacy technologies.

How to Install IE Tab:

  1. Open Chrome and go to the Chrome Web Store.
  2. Search for and install the IE Tab extension.
  3. After installation, click the IE Tab icon to open a new tab with Java support.

Note: IE Tab may require an additional plugin installation. Follow the extension’s instructions for setup.

3. Installing Older Versions of Chrome (Not Recommended)

Technically, you could use an outdated version of Chrome that still supports NPAPI, but this approach is highly insecure and not recommended. Older browser versions may have vulnerabilities, so this method should only be used at your own risk and ideally on isolated systems.

4. Use a Virtual Machine

If Java support is essential, consider setting up a virtual machine with Windows and a browser that supports NPAPI. A virtual machine allows you to isolate outdated technologies from your main operating system, making it a safer option.
