\section{Background}
\label{sec:background}

The current version of Mozilla (1.2.1, on 12 December 2002) is a
useful improvement over the one that comes with Red Hat 8.0.  Here I
give a quick guide on how to install it, set up the Acrobat Reader,
the \acro{JRE} plugin, and install the Macromedia Flash 6 plugin.

I will also explain some of the good features of Mozilla.


\subsection{The Automounter}
\label{sec:automounter}

There is a program called the \texttt{automounter} which automatically
mounts local and network file systems.  The setup is via our \LDAP
directory service, and it includes the ftp site on our server
\texttt{ictlab}, which is accessible on your computer when you access
the directory \texttt{/home/nfs}.  So for example, the
\texttt{redhat-8.0} directory is at \texttt{/home/nfs/redhat-8.0}, and
Red Hat updates are available at \texttt{/home/nfs/redhat-8.0/updates}.


\section{Procedure}
\label{sec:procedure}


\subsection{Installing Mozilla}
\label{sec:installing-mozilla}

We have the Mozilla software packages on our server \texttt{ictlab},
but you can download them from \url{http://www.mozilla.org/releases/}
if you are at home.

\begin{enumerate}
\item Change to the mozilla directory:
  \begin{alltt}
$ \textbf{cd /home/nfs/mozilla}
  \end{alltt}%$

\item and install mozilla:
  \begin{alltt}
$ \textbf{sudo rpm -Uhv *.rpm}
  \end{alltt}%$
\end{enumerate}

\subsection{Installing the Java SDK}
\label{sec:jdk}

Note that here we will install the Java \acro{SDK} and Java run time
environment, to be used by the browser.

\begin{enumerate}
\item Change to the directory on \texttt{ictlab} which contains the
  \acro{JDK}:
  \begin{alltt}
$ \textbf{cd /home/nfs/jdk}
  \end{alltt}%$

\item and install it:
  \begin{alltt}
$ \textbf{sudo rpm -Uhv j2sdk-1_4_1_01-fcs-linux-i586.rpm}
  \end{alltt}%$
\item Now include the executables on your \texttt{PATH} by adding
  these lines (shown below) to your \texttt{/etc/profile} login script:
  \begin{alltt}
$ \textbf{xhost +localhost}
$ \textbf{sudo -v}
$ \textbf{sudo emacs /etc/profile &}
  \end{alltt}%$
   Before the line that says:
  \begin{alltt}
unset pathmunge
  \end{alltt}
  add the lines:
  \begin{alltt}
JAVA_HOME=$(echo /usr/java/j2*)
pathmunge $JAVA_HOME/bin after
export JAVA_HOME
  \end{alltt}

\item Finally, add the plugin to Mozilla's plugin directory.  We
  create a \emph{symbolic link} (see the handout on symbolic links: we
  cover this topic soon):
  \begin{alltt}
$ \textbf{cd /usr/lib/mozilla-1.2.1/plugins}
$ \textbf{sudo ln -s \bs
../../../java/j2sdk1.4.1_01/jre/plugin/i386/ns610/libjavaplugin_oji.so .}
  \end{alltt}
  Note: I just keep pressing the \key{tab} key; I do not memorise this
  file name!
\end{enumerate}


\subsection{Adding Macromedia Flash 6}
\label{sec:flash-6}

If you read the release notes for Mozilla 1.2.1, it says that we
should really use Macromedia Flash version 6, not the current version
5.  You can find a link to the download site for Flash 6 from the
Mozilla release notes, but I reproduce it here:
\url{http://www.macromedia.com/software/flashplayer/special/beta/}.

To install it from our server:
\begin{enumerate}
\item Change to your \texttt{/tmp} directory:
  \begin{alltt}
$ \textbf{cd /tmp}
  \end{alltt}%$

\item unpack it:
  \begin{alltt}
$ \textbf{tar xvzf /home/nfs/mozilla/install_flash_player_6_linux.tar.gz}    
  \end{alltt}%$
\item Then begin the installation:
  \begin{alltt}
$ \textbf{cd install_flash_player_6_linux}
$ \textbf{sudo ./flashplayer-installer}
  \end{alltt}

\item Accept defaults, except when it asks you where it should be
  installed (it offers \texttt{/usr/lib/mozilla}), say
  \texttt{/usr/lib/mozilla-1.2.1}
\end{enumerate}


\subsection{Installing the Acrobat reader 5.0.6}
\label{sec:acrobat}

Note first that Adobe's Acrobat reader does not work with Unicode; it
would not work for me until I set my locale to US English\@.  If that
is okay for you, then proceed.  I have mixed feelings about this
software; sometimes I like it, othertimes I find it does not work
very well.  I use it nonetheless.  You can download the acrobat reader
from \url{http://www.adobe.com}, or you can install it from our
server, \texttt{ictlab}.
\begin{enumerate}
\item Change to your \texttt{/tmp} directory:
  \begin{alltt}
$ \textbf{cd /tmp}
  \end{alltt}%$

\item untar the tarball:
  \begin{alltt}
$ \textbf{tar xvzf /home/nfs/adobe/linux-506.tar.gz}
  \end{alltt}%$

\item install it, accepting defaults:
  \begin{alltt}
$ \textbf{sudo ./INSTALL}
  \end{alltt}%$

\item Create a symbolic link to it onto your \texttt{PATH}:
  \begin{alltt}
$ \textbf{sudo ln -s /usr/local/Acrobat5/bin/acroread /usr/local/bin}
  \end{alltt}%$

\item Optionally, you can install the Chinese fonts:
  \begin{alltt}
$ \textbf{cd /tmp}
$ \textbf{tar xvzf /home/nfs/adobe/fonts-5.0.6/chtfont.tar.gz}
$ \textbf{cd CHTKIT}
$ \textbf{sudo ./INSTLANG}
  \end{alltt}
  Accept defaults and you are done.
\item Setting the language to \texttt{en\_US}:  Edit the file
  \texttt{/etc/sysconfig/i18n}, and change the line:
  \begin{alltt}
LANG=en_US.UTF8
  \end{alltt}
  to:
  \begin{alltt}
LANG=en_US
  \end{alltt}

\item To apply this change permanently, you may need to reboot, but
  you can apply it to your present session by typing:
  \begin{alltt}
$ \textbf{export LANG=en_US}
  \end{alltt}%$
  and try the acrobat reader on some PDF document you have:
  \begin{alltt}
$ \textbf{acroread workshop-notes.pdf}
  \end{alltt}%$

\item To test the plugin in the browser, you need to start mozilla
  with \texttt{LANG} set to \texttt{en\_US}:
  \begin{alltt}
$ \textbf{mozilla}
  \end{alltt}%$
  After you reboot, you can start Mozilla by clicking on the
  globe symbol in the panel at the bottom of your screen, and the
  acrobat reader should work.
\end{enumerate}

\subsection{Testing Mozilla}
\label{sec:testing}

Now you are ready to check that everything is set up right:
\begin{enumerate}
\item Start Mozilla by clicking on the globe in your panel (the tool
  bar at the bottom of your screen)

\item Select \textsf{Help}$\longrightarrow$\textsf{About Plugins}
\item Verify that you can see:
  \begin{enumerate}
  \item \texttt{Java(TM) Plug-in 1.4.1\_01-b01}
  \item \texttt{nppdf.so}
  \item Flash version 6
  \end{enumerate}
\item Verify that the acrobat reader works on web documents.
\end{enumerate}

\section{Selecting useful options in Mozilla}
\label{sec:mozilla-options}

Mozilla has some nice features that you should enable.  You can also
set your home page:

\begin{enumerate}
\item Click on \textsf{Navigator} and set your home page to
  \url{http://nicku.org/ossi/}.
\end{enumerate}
You should be aware that finally, full screen mode works in Linux\@.
Press \key{F11} to toggle full screen mode.

\subsection{Tabbed Browsing}
\label{sec:tabbed-browsing}

Tabbed browsing is a nice feature.  Each web page opens in the same
browser frame, but in another tab.  Try it out:
\begin{enumerate}
\item Select \textsf{Edit}$\longrightarrow$\textsf{Preferences}
\item Click on the triangle next to \textsf{Navigator} and click on
  \textsf{Tabbed Browsing}.
\item Click on the two check boxes at the bottom under ``Open tabs
  instead of windows for''
\end{enumerate}
Now when you click on a link with the middle mouse button (or both
buttons if you have only two), the web page will open in a new tab.


\subsection{Some other Miscellaneous Settings}
\label{sec:misc}
\begin{enumerate}
\item If you are developing web pages, then it is important to
  increase the checking for changes in the web document.  I have the
  setting under \textsf{Advanced}$\longrightarrow$\textsf{Cache} set
  to ``Compare the page in the cache to the page on the network'' to
  ``Every time I view the page''.
\item Under \textsf{Advanced}$\longrightarrow$\textsf{Proxies}, I
  strongly suggest using Richard Yim's proxy configuration script.
  Select ``Automatic proxy configuration file'' and enter:
  \url{http://tyintra.vtc.edu.hk/proxy.proxy}.
\item Set your search engine to Google:
  under \textsf{Navigator}$\longrightarrow$\textsf{Internet Search},
  select ``Search using: Google''.
\end{enumerate}

\subsection{Additional features Mozilla has that IE Lacks}
\label{sec:advantages}

John Dvorak from PC Magazine makes an interesting comparison of
Mozilla with IE at this article:
\url{http://www.pcmag.com/article2/0,4149,715464,00.asp}.  The main
features he points out are (I wouldn't know; I use IE for nothing but
for applying Windows updates):
\begin{itemize}
\item You can expand the font size for \emph{any} fonts in Mozilla
\item You can block pop-up, pop-behind windows (go to
  \textsf{Advanced}$\longrightarrow$\textsf{Scripts \& Plugins} and
  deselect ``Allow scripts to: Open unrequested windows'', among other
  choices).
\item Mozilla is standards compliant.  Microsoft don't bother much with
  standards in IE\@.
\item Printing works better in Mozilla: it doesn't cut off the right
  hand side of the page when you print.
\end{itemize}
