How to install and set up Firefox 4.0 beta3 on OpenSolaris build 111 as of August 25, 2010

I fortunately got help from the Mozilla community and
other websites. Many thanks for their support. Well, I
enter into the main topics.

1. You will need to go to the URL given below and get the
   package firefox-4.0b3.en-US.opensolaris-i386-pkg.bz2.
   http://releases.mozilla.org/pub/mozilla.org/firefox
   /releases/4.0b3/contrib/solaris_pkgadd

2. Then you will need to unzip and install firefox-4.0b3.
   en-US.opensolaris-i386-pkg.bz2 and the command
   lines are given below.

   # bunzip2 -d firefox-4.0b3.en-US.opensolaris-i386-pkg.bz2
   # pkgadd -d firefox-4.0b3.en-US.opensolaris-i386-pkg

3. I referred to the useful website given below and
   could set up Firefox 4.0 beta3. I deeply appreciate
   what he has done. The URL and the command lines
   are given below.
   http://baian-space.blogspot.com/2009/06/realplayer-
   11-gold-with-opensolaris.html

   # cp /opt/sfw/share/applications/firefox.desktop /usr/share/applications
   # cp /opt/sfw/share/pixmaps/firefox-icon.png /usr/share/pixmaps

4. Then I referred to the helpful website given below and
   could add the Java plugin and other plugins into the
   Mozilla plugins. The URL and the command lines are
   given below.
   http://opensolaris.org/jive/thread.jspa?messageID
   =454933

   # mkdir /opt/sfw/lib/firefox/plugins
   # ln -s /usr/java/jre/lib/i386/libnpjp2.so /opt/sfw/lib/firefox/plugins
   # cp /usr/lib/firefox/plugins/* /opt/sfw/lib/firefox/plugins

5. After that, you may localize Firefox 4.0 beta3 for your
   language environment. I referred to the practical websites
   given below and would like to express my appreciation to
   them for their work. I actually went to the URL given
   below, got firefox-4.0b5pre.ja.langpack.xpi, and
   modified install.rdf in the .xpi file, or more specifically,
   changed the value of minVersion into 4.0b3pre. Please
   relax your caution against tentatively taking my native
   tongue as an example because this way can be applied
   in many other languages. The URL and the command
   lines are given below.

   #JLPAPPLY
   http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly
   /latest-mozilla-central-l10n/

   $ cd Downloads
   $ mkdir work
   $ cd work
   $ unzip ../firefox-4.0b5pre.ja.langpack.xpi
   $ gedit install.rdf
     <EXAMPLE>
      <em:minVersion>4.0b3pre</em:minVersion>
   $ find -print0 | xargs -0 zip -9 ../ja.xpi -@

   Now you can localize Firefox 4.0 beta3 for your language
   environment, adding on ja.xpi to the language pack in
   Firefox and setting general.useragent.locale, which is
   the entry in about:config, of ja-JP.

Finally I am happy to assist you to install and set up
Firefox 4.0 beta3 on OpenSolaris build 111.
