Why don't Java-based tools work with Chrome now?

Beginning with Chrome version 42, Google disabled by default a technology called NPAPI, a technology relied upon by Java to work with web browsers. This blocks the use of Java with Chrome.

Depending upon the version of Chrome installed on your computer, you may be able to re-enable Java in Chrome:

  • for Chrome versions 42.x through 44.x: See below for instructions that re-enable Java.
  • for Chrome versions 45.x and higher: You cannot use Java with Chrome.

How can I make Java work in Chrome again?

These instructions only work in Chrome versions 42.x through 44.x.

You can re-enable NPAPI—and therefore, Java—by:

  1. Using Chrome, follow this link: chrome://flags/#enable-npapi
    or copy-and-paste that link into the web address box in Chrome and then press return.
  2. On the page that loads, click the "Enable" link.

This will also let other NPAPI-based plugins work again, if you have others installed.
