Netscape Navigator 9 Released

Nearly 3 months after we reviewed Netscape 9.0b2, the final version of Netscape Navigator 9 has been released today. Netscape Navigator uses the same Gecko engine as Firefox 2 (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20071015 Firefox/ Navigator/9.0) and is available for Windows, Mac OSX or Linux. Further since it is based on Firefox 2, extensions are cross-browser compatible. Any Firefox 2 extension will work with Netscape Navigator 9 as will a Netscape Navigator 9 extension work with Firefox 2.

  1. I am trying to write a Firefox extension with a Java backend, but all the documentation and examples I could find only work for Firefox 1.* (e.g., MIT’s Simile project ( and the Mozilla documentation’s example (

    Is there any documentation or examples for Firefox 2.0.*? I found a blog post about changes to the way developers have to connect to Java (
    but it referred me to, which seemed to be C++, not Java.

    So, do I need to learn JNI or something to write a simple extension?! C++? Is there any easy way to run a Java program in a JavaScript extension?
