The Java plug-in for web browsers relies on the cross platform plugin architecture NPAPI, which has long been, and currently is, supported by all major web browsers. Google announced in September 2013 plans to remove NPAPI support from Chrome by "the end of 2014", thus effectively dropping support for Silverlight, Java, Facebook Video and other similar NPAPI based plugins. Recently, Google has revised their plans and now state that they plan to completely remove NPAPI by late 2015. As it is unclear if these dates will be further extended or not, we strongly recommend Java users consider alternatives to Chrome as soon as possible. Instead, we recommend Firefox, Internet Explorer and Safari as longer-term options.
Starting with Chrome version 37, Chrome is available in 64-bit format on Windows. When running 64-bit Chrome, the user must also have 64-bit Java installed.

A 64-bit browser is required to run 64-bit Oracle Java on Mac OS X. Chrome 64-bit for Mac became available with Chrome Version 39. For more information, see 64-bit Chrome (blog.chromium.org).
Starting with Chrome version 35, NPAPI (Netscape Plug-in API) support was removed for the Linux platform. For more information, see Chrome and NPAPI (blog.chromium.org).
Firefox is the recommended browser for Java on Linux.
