| Mozilla Foundation Browsers: |
The Mozilla Foundation has released three browsers covered in this tutorial:
-
 |
Mozilla: This was the first
open source browser released from the Netscape group. Mozilla is no
longer developed. The follow-on project which develops an integrated
web browser, HTML editor, email client, address book and chatzilla
client is SeaMonkey. |
 |
SeaMonkey: Integrated web application suite (browser, html editor, email) derived from the former Mozilla source code but updated with Firefox components. |
 |
Firefox: A high performance, feature rich, standards based web browser. |
| Mozilla and Firefox Installation: |
- YUM: yum -y install firefox
- RPM: rpm -ivh firefox-1.XXX.YYY.rpm
- RPM: rpm
-ivh mozilla-1.7.XXX.YYY.rpm mozilla-mail-1.7.XXX.YYY.rpm
mozilla-dom-inspector-1.7.XXX.YYY.rpm mozilla-nss-1.7.XXX.YYY.rpm
mozilla-nspr-1.7.XXX.YYY.rpm mozilla-nspr-1.7.XXX.YYY.rpm
mozilla-js-debugger-1.7.XXX.YYY.rpm
- APT: apt-get install mozilla-thunderbird
| View Browser Configuration: |
List available options. Type the URL: about:config
This will allow you to modify the
advanced configuration options found in the various Mozilla
configuration files. Right click on the value to alter and a dialog box
will appear to allow changes.
-
The preferences are stored in the file /home/user-id/.mozilla/firefox/..../prefs.js.
| Mozilla / Firefox Environment Variables: |
-
| Environment Variable |
Description |
| MOZILLA_FIVE_HOME |
Home directory path for browser |
| MOZILLA_PLUGIN_PATH |
Directory path for browser plug-ins.
(Often $MOZILLA_FIVE_HOME/plugins) |

Proxy configuration: Many corporate networks rely on SOCKS proxy servers
for access to the internet. Typically a Proxy Auto Configuration (PAC)
script is issued to be registered
with the browser. These scripts are usually targeted to Microsoft
Explorer of Netscape Navigator (4.x) specifically. Try the proxy script:
"Edit" + "Preferences" and select "Advanced (+)" and "Proxies" +
"Automatic proxy configuration URL", enter the script location
and select the "Reload" button.
If it works, great your ready to surf.
If your corporation uses a proxy directly, enter it under "Manual
proxy configuration".
If using a script and it does not work, use the command
"wget http://proxy-url.domain.com/proxy-script.pac" to
download the proxy script. Examine the file proxy-script.pac.
Burried in the logic of the script is usually the explicit listing of a
proxy server which can be entered under the Mozilla manual configuration.
If you are at a corporation using a firewall and have direct access,
I'm jealous and you have no need for proxy configuration.
Firefox extensions are supplemental programs which are installed within
Firefox from the Mozilla web site. Extensions are available for
Blogging, Web Developer Tools, Dictionaries, Download Tools,
Editing and Forms, Image Browsing, Kiosk Browsing Languages,
Message Reading, Navigation,
News Reading, Privacy and Security, Search Tools,
Website Integration, XUL Applications, ...
To add an extension:
- Allow the extensions website to install software:
Select "Edit" + "Preferences" (or "Tools" + "Options" on newer systems)
Check "Allow web site to install software" then
press the corresponding "Allowed Sites" button. |
Enter the "allowed" site. |
|
|
- Select and install an extension: Select "Tools" + "Extensions" + "Get more extensions".
This brings up a web page from which you may choose the extension which suits your needs.
| Configuring Java support: |
Install Sun SDK (1.6): See Java SDK download/install
(J2RE: JAVA 2 Runtime Environment RPMs for Mozilla)
Mozilla and SeaMonkey Configuration:
-
Java VM support:
- Java (generic):
- x86_64: ln -s /usr/java/latest/jre/lib/amd64/libnpjp2.so /usr/lib64/mozilla/plugins/
- i386: ln -s /usr/java/latest/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/
(Where the "latest" directory is another soft link which points to a specific release. The Java 1.6 RPM configures itself this way.)
- Java 1.6 (i386): ln -s /usr/java/jdk1.6.0/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/
- Java 1.5 (i386): ln -s /opt/jdk1.5.0_07/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/
- Java 1.4 (i386): ln -s /usr/java/j2sdk1.4.1_02/jre/plugin/i386/ns610/libjavaplugin_oji.so /usr/lib/mozilla-1.0.2/plugins/
Supports mime type: application/x-java-vm
(Required for Microsoft Exchange OWA webmail support.)
If the directory /usr/lib/mozilla/plugins/ does not exist, create it or use the directory which explicitly states your version of Mozilla. i.e.: /usr/lib/mozilla-1.0.2/plugins/. Installing the "plugger" RPM will generate the directory /usr/lib/mozilla/plugins/.
Restart the browser to pick-up the new plug-ins. Verify with the URL "about:plugins".
[Potential Pitfall]: Many versions of the
Java shared object plugin libjavaplugin_oji.so may crash your version of Mozilla.
The one listed above will work.

Java web start configuration: Application handler for mime type: application/x-java-jnlp-file
JNLP: Java Network Launching Protocol
Java applets run within the browser controlled environment but JNLP applications do not.
JNLP applications run in the same sandbox as applets, with several minor extensions like allowing them to load and save files explicitly selected by the user.
Only signed applications can be configured to have additional or even all permissions.
Some benefits of JNLP include seamless version updating of internet distributed applications and greater control of memory allocation to the Java virtual machine.

| Firefox, Mozilla and SeaMonkey Plug-ins: |
Plug-ins display various media types within a web page or if a link to
a media file, it can display the content within the browser window.
While there are many browsers available for Linux, most plug-ins conform to the
Netscape 4 plug-in architecture. Thus this tutorial should apply to most
Linux web browsers.
List active plug-ins, type the URL: about:plugins
Note: Restart the browser before using a newly installed plug-in.
The browser must be restarted to be aware of the new plug-in.
Plug-ins are located in:
- System wide availablility:
- /usr/lib/mozilla/plugins/
Note: On older 64 bit systems this directory held 32 bit plug-ins.
On Ubuntu 11.04 this directory holds 64 bit plug-ins and /usr/lib64/ is a soft link to /usr/lib/
- 32 bit: /usr/lib32/mozilla/plugins/
- 64 bit: /usr/lib64/mozilla/plugins/
- Available to the local user: ~/.mozilla/plugins/
On my system this holds 32 bit libraries although this may not be the rule.
Downloads: The easiest way to download the appropriate
components is with the YUM, the "Yellow Dog" network RPM package
installer. See YoLinux tutorial on YUM configuration
and how to add the FreshRPM.net site to your download list which will
allow you to have access to the media player applications which are not
included in the base install.
| Universal Application Plug-ins: |
These universal plug-ins can accept extenstion to handle other media types by making additions to the mozplugger (or plugger) configuration file /etc/mozpluggerrc (or /etc/pluggerrc) and installing the application.
- MozPlugger: (current Linux distributions and browsers)
Home page and downloads:
http://mozplugger.mozdev.org/
Current Linux distributions have a general media plug-in manager called mozplugger which replaces the older plugger.
Config file: /etc/mozpluggerrc
Plugins directory: /usr/lib/mozilla/plugins
(x86_64: /usr/lib64/mozilla/plugins)
Note that you may have to extablish a soft link for Firefox upgrades.
i.e.: ln -s /usr/lib/mozilla/plugins/mozplugger.so /opt/firefox/plugins
This plugin uses various Linux media viewers for display of various mime types within mozilla.
Installation:
- RPM based OS: YUM install: yum -y install mozplugger
(Red Hat Enterprise Linux/Fedora 1-9/CentOS)
- Debian/Ubuntu: APT install: apt-get install mozplugger
- Plugger: (legacy Red Hat 7-9.0)
Home page and downloads: http://fredrik.hubbe.net/plugger.html
Plugger is a Mozilla plug-in that ties many of the Linux applications to
Mozilla so that they can be viewed within the browser rather than by launching
a separate "helper" application.
The plugin "plugger" installs with Red Hat 7-9 and handles most of the
file types including pdf (requires xpdf or evince), Postscript (requires ggv. Note older versions of Linux used gv ghostview. Newer versions tend to use ggv Gnome ghostview.),
mpeg (requires xanim), avi (requires xine or mplayer. If using xine, use "xine -p".),
midi (timidity), wav (play), tiff (eog), bmp (eog), ...
Plugger has the following media player dependencies: xloadimage (view image in X11 display),
sox (sound sample translator) and mikmod (play soundtrack).
These should be part of the Linux installation.
Plugger will handle the following mime types: wav, midi, mpeg, mov, avi, png, tiff, bmp, pdf, ps, wav, au, mp3 etc.
(partial list) [Description - suffixes man page]
Plugger is configured to use the following applications: eog, xpdf, ggv, play, playmidi,
xanim, xine, mtvp, timidity, xmp, mikmod, mpg123, xloadimage and display.
Download the Mozilla plug-in, plugger (rpm) - part of Red Hat Linux base OS
i.e.: http://mirrors.usc.edu/pub/linux/distributions/redhat/redhat/linux/9/en/os/i386/RedHat/RPMS/plugger-4.0-23.i386.rpm (RH 9.0)
Download media support application RPMs:
If the audio file plays back
at too high a speed, then use esdplay instead of play.
While Plugger is pre-configured to handle many mime types, there are gaps
in format coverage. See file: /etc/pluggerrc for mime types and
applications configured to work with plugger.
Adding applications to /etc/pluggerrc
-
..
...
application/vnd.ms-excel: xls, xlb: Microsoft Excel Document
nokill exits: oocalc "$file" - Add this line
repeat swallow(PluggerGnumeric) fill: gnumeric --class PluggerGnumeric "$file"
...
..
|
Note: This seems to have been an oversight in Red Hat 9.0, plugger-4.0-23.
Fix for Red Hat 8.0/9.0. The postscript viewer gv (ghostscript) has
been supersceded by ggv (Gnome ghostscript) Update plugger reference
by changing all references of gv to ggv:
-
..
...
application/pdf: pdf: PDF file
application/x-pdf: pdf: PDF file
text/pdf: pdf: PDF file
text/x-pdf: pdf: PDF file
repeat swallow(documentShell) fill: acroread -geometry +9000+9000 -xrm '+useFrontEndProgram' "$file"
repeat swallow(Xpdf) fill: xpdf -g +9000+9000 "$file"
repeat swallow(ggv) fill: ggv -safer -quiet -antialias -geometry +9000+9000 "$file" 2>/dev/null

repeat swallow(Pageview) fill: pageview "$file"
...

After making changes to the plugger configuration file (/etc/mozpluggerrc or /etc/pluggerrc), remove the following auto generated configuration file (various names have been used) and restart the browser.
- ~/.mozilla/firefox/pluginreg.dat
- ~/.mozilla/pluginreg.dat
- ~/.netscape/plugin-list
Note that web server support for additional mime types is added to /etc/mime.types or can be added with the directive "AddType" in the Apache httpd configuration file httpd.conf. Restart the httpd daemon after any configuration change.

Test SVG plug-in with:
- Croczilla.com: examples - these work with Firefox 1.5+ native support!
- Adobe test page or with file SVGAbout.svg included with tar file. (does not work with plug-in or with Firefox 1.5+ native support.)
Navigation controls: (didn't work for me)
- Pan: ALT + mouse drag
- Pan horizontal/vertical only: Shift + ALT + mouse drag
- Zoom: ctrl + click and point mouse at point to zoom in.
- Zoom region: ctrl + click and drag mouse at rectangle to zoom in.
- Right click for pop-up menu.
[Potential Pitfall]: This plug-in never worked for me and gave me the following errors using their two examples:
-
XML Parsing Error: not well-formed
Location: http://www.adobe.com/svg/svgfiles/svgtest.svgz
Line Number 1, Column 1:

AND:

What kind of crap Adobe plug-in and examples are these!!! I tried FC3
with firefox-0.10.1-1.0PR1.20 and firefox-1.0.7-1.1.fc3 and both browsers
crashed with the plug-in. Using Firefox version 1.5 downloaded from
Mozilla.com with native SVG support, the Adobe examples failed but the
Croczilla.com examples worked.
What works: Firefox 1.5+ native support or helper application "Eye of Gnome" eog.

| Configuring Mozilla/SeaMonkey Helper Applications: |
The configuration described below and the script shown,
applies to the Mozilla/SeaMonkey browser only.
The Firefox browser does not accept user defined applications for mime type handling.
Firefox only accepts plug-ins and thus any additional support must be
configured through the "MozPlugger" plug-in.
Links to file types not handled by the Mozilla/SeaMonkey browser or e-mail attachments
not handled by the Mozilla/SeaMonkey e-mail client are opened by helper applications.
The file mime type and/or file extension identifies the file type.
This section of the tutorial shows how to configure the Mozilla/SeaMonkey web
browser to support additional file types.
This is different than using a plug-in which allows for the file to be viewed
within the browser. Helper applications are launched as separate applications.
The following configuration instructions for allowing Mozilla
to handle various media formats ultimately results in the modification
of the files $HOME/.mailcap, $HOME/.mime.types and $HOME/.mozilla/user-id/xxxxxx.slt/mimeTypes.rdf.
-
Mozilla/SeaMonkey: Edit + Preferences + choose: Navigator + Helper Applications:
Downloads: The easiest way to download the appropriate
components is with the YUM, the "Yellow Dog" network RPM package
installer. See YoLinux tutorial on YUM configuration
and how to add the FreshRPM.net site to your download list which will
allow you to have access to the media player applications which are not
included in the base install.
Mime Types and Applications:
- application/octet-stream: This mime type is very vague but used all
the time especially by Microsoft e-mail clients like Outlook.
There is no single application to handle the multitude of file
types which are sent with this mime type. Only the file extention or actual
file interrogation of its magic number (file command) can reveal the contents.
The following script and program attempt to launch the appropriate application
for this mime type.
-
Description: Octet-Stream Handler

MIME Type: application/octet-stream
Application: /opt/bin/mozilla-octet-stream.sh
|
Now why would an mpeg movie or a jpeg image ever be sent as an octet-stream? Either its
a Microsoft product which sent it or a misconfigured server is unaware of the
mime type or "dumbed down" to avoid having users use this media type.
This solution uses a shell script /opt/bin/mozilla-octet-stream.sh and executable /opt/bin/suffix compiled from the source below.

One may also use the Bash shell funtion:
-
You may replace the line in script above:
FILE_EXTENTION=`/opt/bin/suffix "$1" | tr '[:upper:]' '[:lower:]'`
|
with the following code segment:
function getfileext () {
file=$1
echo ${file##*.}
}
FILE_EXTENTION=`getfileext $1`
|
This may be used instead of the following program "suffix" below except that this
shell function will not work on file names with embedded blanks.
Using the program suffix is superior than using the bash function
getfileext ().

Notes for Acrobat Reader 5.0: (legacy)
- The Acroread PDF viewer includes a Netscape plug-in nppdf.so but I never got it to work. The Adobe acroread application as configured above works like a champ.
- [Potential Pitfall]:
Acroread 5.0 - The default Red Hat 8.0/9.0 UTF-8 language environment
variable is incompatable with Adobe Acroread. One must set "LANG" to
something else. i.e.: export LANG=C
It can be set in your login profile or near the beginning of the shell script /opt/Acrobat5/bin/acroread
- Red Hat (8,9,E3,E4) comes with the plug-in "plugger" which will launch the xpdf
viewer which seems to be just as capable as Adobe Acroread. Acroread has more
printing features.
Evince (/usr/bin/evince) was introduced with Red Hat Enterprise 5.

Locked out after a crash?:
[Pitfall]:
If you experienced a system crash and subsequently rebooted and tried to start
Mozilla but are prevented from using your user profile, you may have to
remove the "lock" file.
The lock file prevents more than one instance of Mozilla from running on a
single profile. It is a symbolic link which will have to be removed before
starting Mozilla. Remove it: rm $HOME/.mozilla/userid/dji9dszq.slt/lock where the funky "slt" directory name will be unique to your user id.
Newer versions of Firefox will also have an additional lock file: ~/.mozilla/firefox/9f2f04yd.default/.parentlock

| Using ssh tunneling and a Remote Proxy: |
You can create an ssh tunnel to a remote system and use the remote system
as a proxy.
Local system: Connect to remote system using ssh and dynamic port forwarding.
-
ssh -D port-number login-id@remote-node
Example:
-
ssh -D 9999 user1@node6.mega-corp.com
This establishes a connection to the remote node and configures traffic on
local port 9999 to be forwarded to the remote system which acts as a proxy
and fulfill the network request.
Mozilla/SeaMonkey Configuration:
- Select "Edit" + "Preferences..."
- On the left hand side of the window select and expand on the browser tree
"Advanced" + "Proxies"
- Select "Manual Proxy Configuration"
- Select "SOCKS V4"
- Set entries:
- Socks Host: localhost
- Port: 9999
Remote system: The service sshd must be running.
Browser requests will be forwarded to local port 9999 through
ssh to the remote node which will fulfill the request. I have tried
this for http web request as well as e-mail POP3 inbound mail and SMTP
outbound mail and it works!
| x86_64 Browser Pitfalls and Fixes: |
The Mozilla/SeaMonkey and Firefox browsers compiled for the x86_64,
64 bit architecture
(AMD Athelon/Opteron/Turion 64 and Intel EM64T) do NOT
support proprietary plug-ins compiled for the i386, 32 bit processor architecture.
This is a problem if you want to use Macromedia Flash plug-ins which are compiled for 32 bit architectures.
The solution is to use the 32 bit
i386 browser binaries (and their dependencies) on the x86_64 version of Linux.
This works because x86_64 Linux (i.e. AMD Athelon)
supports the option to run both 32 bit i386 and 64 bit x86_64 binaries by supplying 32 bit libraries on the 64 bit OS. This is true for both RedHat and Debian/Ubuntu distributions.
RPM based OS Fix: (FC-3 example)
- Remove x86_64 RPMS:
- rpm -e firefox mozplugger
- Install i386 RPMS:
- rpm -ivh firefox-0.10.1-1.0PR1.20.i386.rpm mozplugger-1.6.2-1.i386.rpm
You can also specify the architecture when using YUM for installation: yum -y install firefox.i386
Ubuntu/Debian based OS Fix:
- Remove x86_64 packages:
- dpkg -r firefox mozplugger
- Install i386 packages:
- dpkg -i --force-architecture firefox-3.0......deb
Generic Linux/Unix based Fix:
Download tar file from http://mozilla.com and install to /opt:
- mv firefox-3.0.5.tar.bz2 /opt
- cd /opt
- tar xjf firefox-3.0.5.tar.bz2
If you insist on using x86_64 browser binaries, make sure you:
-
Install Microsoft True Type fonts to correctly render pages targeted for the Microsoft browser and fonts.
