Getting Firefox
|
|
|
|
================================================================================
|
|
|
|
Official Milestone builds of Firefox are published on the release page at
|
|
|
|
http://www.mozilla.com/en-US/firefox/releases/
|
|
|
|
OS/2 releases are not created by Mozilla staff and may appear on the
|
|
page http://www.mozilla.org/ports/os2 before the releases page. Be sure to read
|
|
the release notes linked on the releases page for information on known problems
|
|
and installation issues.
|
|
OS/2 specific problems with this version are listed below.
|
|

================================================================================
|
|
|
|
System Requirements on OS/2
|
|
|
|
================================================================================
|
|
|
|
- This release requires the C runtime DLL (libc063.dll) from
|
|
ftp://ftp.netlabs.org/pub/gcc/libc-0.6.3-csd3.zip
|
|
in order to run. You can unpack them in the same directory as the
|
|
Firefox executable or somewhere else in your LIBPATH.
|
|
|
|
- Minimum hardware requirements
|
|
+ 400 MHz Pentium class processor
|
|
+ 128 MiB RAM plus 128 MiB free swap space
|
|
+ 40 MiB free harddisk space for installation
|
|
plus storage space for disk cache
|
|
+ Graphics card and driver capable of displaying more than 256 colors
|
|
|
|
- Recommended hardware for acceptable performance
|
|
+ 1.0 GHz processor
|
|
+ 512 MiB RAM plus 128 MiB free swap space
|
|
NOTE: Firefox's performance and stability increases the more physical
|
|
RAM is available.
|
|
|
|
- Software requirements
|
|
+ Installation on a file system supporting long file names
|
|
(i.e. HPFS or JFS but not FAT)
|
|
+ OS/2 Warp 4 with Fixpack 15 or later (Warp 3 may work but is unsupported)
|
|
+ MPTS version 5.3
|
|
+ TCP/IP version 4.1
|
|
+ INETVER: SOCKETS.SYS=5.3007, AFOS2.SYS=5.3001, AFINET.SYS=5.3006
|
|
NOTE: Do not attempt to use MPTS & TCP/IP versions below these INETVER
|
|
levels. Although Firefox may seem to start and run normally with older
|
|
stacks, some features Firefox needs are not implemented correctly in
|
|
older MPTS versions, which may result in crashes and data loss.
|
|
|
|
+ Convenience Pack 2 or eComStation 1.0 or later meet these requirements
|
|
out of the box.
|
|
|
|
+ Only Java plugins of version 1.4.1 or 1.4.2 are supported.
|
|
(IBM Java 1.3.1 or earlier will crash the application!)
|
|
|
|
- Useful optional software
|
|
The following packages enable additional features in Firefox. Download
|
|
locations are listed below with a detailed description of the features.
|
|
+ Remote Workplace Server (RWS), version 0.8
|
|
+ Doodle's Screen Saver (DSSaver), version 1.8 or later
|
|
|

Installation Instructions
|
|
|
|
================================================================================
|
|
|
|
Unpack into a clean (new) directory. Installing on top of previously released
|
|
builds may cause problems with Firefox. It is therefore hightly recommended
|
|
to follow the instructions under "Separating profiles from installation
|
|
directory".
|
|
|
|
Note: These instructions do not tell you how to build Firefox.
|
|

|
|
OS/2 Installation Instructions
|
|
------------------------------
|
|
|
|
On OS/2, Firefox does not have an installation program. To install it,
|
|
download the .zip file and follow these steps:
|
|
|
|
1. Click the "Zip" link on the site you're downloading Firefox from to
|
|
download the ZIP package to your machine. This file is typically called
|
|
firefox-x.x.x.en-US.os2.zip where the "x.x.x" is replaced by the
|
|
current Firefox version.
|
|
|
|
2. Navigate to where you downloaded the file and unpack it using your favorite
|
|
unzip tool.
|
|
|
|
3. Keep in mind that the unzip process creates a directory "firefox" below
|
|
the location you point it to, e.g.
|
|
unzip firefox-3.1.en-US.os2.zip -d c:\firefox-3.1
|
|
will unpack Firefox into c:\firefox-3.1\firefox.
|
|
|
|
4. Make sure that you are _not_ unpacking over an old installation. This is
|
|
known to cause problems.
|
|
|
|
5. To start Firefox, navigate to the directory you extracted Firefox to,
|
|
ensure that the C library DLL is copied to the installation directory or
|
|
installed in the LIBPATH, and then double-click the Firefox.exe object.

Tips and Problems
|
|
|
|
================================================================================
|
|
|
|
Running multiple versions concurrently
|
|
--------------------------------------
|
|
|
|
If you want to run more than one copy of Firefox, you have to use the
|
|
-no-remote parameter or set MOZ_NO_REMOTE=1 in your environment.
|
|
|
|
Because various members of the Mozilla family (i.e. SeaMonkey, Mozilla, Firefox,
|
|
Thunderbird, IBM Web Browser) may use different, incompatible versions of the
|
|
same DLL, some extra steps may be required to run them concurrently.
|
|
|
|
One workaround is the LIBPATHSTRICT variable. To run Firefox one can create
|
|
a CMD script like the following example (where an installation of Firefox
|
|
in the directory d:\internet\firefox is assumed):
|
|
|
|
set LIBPATHSTRICT=T
|
|
rem The next line may be needed when a different Mozilla program is listed in LIBPATH
|
|
rem set BEGINLIBPATH=d:\internet\firefox
|
|
rem The next line is only needed to run two versions of the same program
|
|
rem set MOZ_NO_REMOTE=1
|
|
d:
|
|
cd d:\internet\firefox
|
|
firefox.exe %1 %2 %3 %4 %5 %6 %7 %8 %9
|
|
|
|
Similarly, one can create a program object to start Firefox using the
|
|
following settings:
|
|
|
|
Path and file name: *
|
|
Parameters: /c set LIBPATHSTRICT=T & .\firefox.exe "%*"
|
|
Working directory: d:\internet\firefox
|
|
|
|
(One might need to add MOZ_NO_REMOTE and/or BEGINLIBPATH as in the CMD script
|
|
above depending on the system configuration.)
|
|
|
|
Finally, the simplest method is to use the Run! utility by Rich Walsh that can
|
|
be found in the Hobbes Software Archive:
|
|
|
|
http://hobbes.nmsu.edu/h-search.php?key=Run!
|
|
|
|
Read its documentation for more information.
|
|
|
|
|
|
Separating profiles from installation directory
|
|
-----------------------------------------------
|
|
|
|
To separate the locations of the user profile(s) (containing the bookmarks and
|
|
all customizations) from the installation directory to keep your preferences in
|
|
the case of an update even when using ZIP packages, set the variable
|
|
MOZILLA_HOME to a directory of your choice. You can do this either in Config.sys
|
|
or in a script or using a program object as listed above. If you add
|
|
|
|
set MOZILLA_HOME=f:\Data
|
|
|
|
the Firefox user profile will be created in "f:\Data\Mozilla\Firefox".
|
|
|
|
If you are migrating from Mozilla, Firefox's import routine will only find
|
|
the existing Mozilla profile data if MOZILLA_HOME is correctly set to point to
|
|
it.
|
|
|
|
|
|
Other important environment variables
|
|
-------------------------------------
|
|
|
|
There are a few enviroment variables that can be used to control special
|
|
behavior of Firefox on OS/2:
|
|
|
|
- set NSPR_OS2_NO_HIRES_TIMER=1
|
|
This causes Firefox not to use OS/2's high resolution timer. Set this if
|
|
other applications using the high resolution timer (multimedia apps) act
|
|
strangely.
|
|
|
|
- set MOZ_NO_REMOTE=1
|
|
Use this to run two instances of Firefox simultaneously (like e.g. debug
|
|
and optimized version).
|
|
|
|
- set MOZ_NO_RWS=1
|
|
Use this to disable Remote Workplace Server support (see below).
|
|
|
|

|

http://www.os2bbs.com/os2news/Warpzilla.html
|
|
|
|
|
|
Support for WPS objects
|
|
-----------------------
|
|
|
|
Firefox can make use of Rich Walsh's Remote Workplace Server (RWS) library
|
|
to access Workplace Shell objects from the application. This allows helper
|
|
applications for downloaded files to be selected based on their default WPS
|
|
association. In addition, the WPS icons of files will be displayed in the
|
|
download dialog and in directory views.
|
|
|
|
To enable this functionality, Firefox has to find the RWS DLLs. They have to
|
|
be located in a directory on the LIBPATH, in the Firefox directory, or
|
|
already be registered as a WPS class. For eComStation 2 this is already the
|
|
case. If RWS is not yet available on your system, download it from
|
|
http://hobbes.nmsu.edu/h-search.php?key=rws08dll
|
|
|
|
If RWS is found on the system, it is used by Firefox automatically. In case
|
|
you need to disable RWS support, create an environment variable MOZ_NO_RWS and
|
|
set it to 1.
|
|
|
|
|
|
Idle timer for internal cleanups
|
|
--------------------------------
|
|
|
|
If Doodle's Screen Saver (DSSaver) v1.8 or later is installed, Firefox can
|
|
determine how long the user has been inactive. If the user has been inactive
|
|
for a while, cleanup operations are performed (e.g. on the browsing history)
|
|
and reloads of "Live Bookmarks" are suspended.
|
|
|
|
DSSaver can be downloaded from
|
|
ftp://ftp.netlabs.org/pub/dssaver/dssaver_v18.zip
|
|
|
|
|
|
Setting the OS/2 default browser
|
|
--------------------------------
|
|
|
|
The default web browser can be set using WPS URL objects. The properties
|
|
notebook of every URL object contains a "Browser" tab where the browser
|
|
executable can be selected. Any changes to these settings will be stored and
|
|
reflected in all URL objects once the user presses the "Set Default" button.
|
|
|
|
Two small applications make this change a bit easier and provide options to also
|
|
set default programs for other types of internet-related activities:
|
|
|
|
- ConfigApps
|
|
http://hobbes.nmsu.edu/h-search.php?key=configapps1_1
|
|
|
|
- Internet Application Integration
|
|
http://7cities.net/~mckinnis/os2/
|
|
|
|
|
|
Changed font handling
|
|
---------------------
|
|
|
|
To be able to display text, Firefox cannot make use of normal OS/2 routines
|
|
but has to use FreeType and FontConfig. This has the advantage that text can
|
|
be displayed with antialiasing, but at the same time has some caveats:
|
|
|
|
- Firefox cannot make use of OS/2 fonts like WarpSans and others which
|
|
are not available in Type1 or TrueType format. It is therefore
|
|
recommended to install the "Workplace Sans" font from
|
|
http://users.socis.ca/~ataylo00/creative/fonts/
|
|
or
|
|
http://hobbes.nmsu.edu/h-search.php?key=wpsu_ttf
|
|
which Firefox will use as a replacement of WarpSans.
|
|
|
|
- Display of text in some languages (e.g. Arabic) does not yet take into account
|
|
that different forms of some characters exist.
|
|
|
|
To tweak the appearance of text, you can add two preferences, preferably using
|
|
about:config.
|
|
|
|
- gfx.os2.font.antialiasing (Boolean)
|
|
This preference controls whether antialiasing is enabled, and defaults to
|
|
true.
|
|
|
|
- gfx.os2.font.hinting (Integer)
|
|
This preference controls the hinting level, and can be between 0 (no hinting)
|
|
and 3 (full hinting). The default value is 2.
|
|
Font hinting improves the contrast of displayed text, but may produce poor
|
|
results for certain characters of some fonts, most notably the OS/2 version
|
|
of "Times New Roman".
|
|
|
|
Note that these preferences only take effect when a font gets used for the first
|
|
time, so you may need to restart the application to see the full effect.
|
|
|
|
|
|
Known Problems of the OS/2 version
|
|
----------------------------------
|
|
|
|
Cross-platform problems are usually listed in the release notes of each
|
|
milestone release.
|
|
|
|
- Printing to normal OS/2 printer queues had to be disabled. It was slow even
|
|
for simple pages and used huge amounts of RAM, so that in most cases the
|
|
application crashed, see https://bugzilla.mozilla.org/show_bug.cgi?id=415522.
|
|
While the queues are still displayed in the printing dialog, any printing
|
|
operation will instead create a PDF file. By default this file is placed on
|
|
the Desktop, with the name Firefox_<date>_<time>.pdf, where <date> and
|
|
<time> are replaced by the current system time. If you want to use another
|
|
name, select "Print to file" before pressing the Print button.
|
|
The resulting PDF file can be printed using applications like Lucide, Acrobat
|
|
Reader, or GSview.
|
|
|
|
- Fonts with names containing special characters (like Asian Unicode names)
|
|
will not display correctly in the list of fonts in the Options panel.
|
|
|
|
- Firefox will beep when copying more than 64 kB of text to the clipboard.
|
|
This is to alert users that many applications (most notably the system
|
|
editor, EPM, and applications running in VIO windows) cannot paste more
|
|
than this.
|
|
|
|
Other known problems can be found by following the link "Current Open Warpzilla
|
|
Bugs" on the OS/2 Mozilla page <http://www.mozilla.org/ports/os2/>.
