Official Milestone builds of Firefox are published on the release page at

|
|
|

http://www.mozilla.org/products/firefox/releases/
|
||
|
|
|

OS/2 releases are not created by Mozilla.org staff and may appear on the page
|
||
|

http://www.mozilla.org/ports/os2 before the releases page. Be sure to read the
|

Firefox release notes linked on the releases page for information on known

System Requirements on OS/2
|
||
|
|
|
||
|
|
================================================================================
|
||
|
|
|
||
|
|
- This release requires updated C runtime DLLs (libc-0.5.1) from
|
||
|
|
http://www.innotek.de/products/gccos2/download/gccos2download_e.html
|
||
|
|
in order to run. By default the installation routine places them in \OS2\DLL
|
||
|
|
on your bootdrive, but you can put them in the same directory as Firefox's
|
||
|
|
executable, or somewhere else in your LIBPATH.
|
||
|
|
|
||
|
|
- Minimum hardware requirements
|
||
|
|
+ Pentium class processor
|
||
|
|
+ 64 MiB RAM plus 64 MiB free swap space
|
||
|
|
+ 35 MiB free harddisk space for installation
|
||
|
|
plus storage space for disk cache
|
||
|
|
|
||
|
|
- Recommended hardware for acceptable performance
|
||
|
|
+ 500 MHz processor
|
||
|
|
+ 256 MiB RAM plus 64 MiB free swap space
|
||
|
|
NOTE: Firefox's performance and stability increases the more physical
|
||
|
|
RAM is available. Especially for long sessions 512 MiB of memory is
|
||
|
|
recommended.
|
||
|
|
+ Graphics card and driver capable of displaying more than 256 colors
|
||
|
|
|
||
|
|
- 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
|
||
|
|
+ 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.

Installation Instructions
|
||
|
|
|
||
|
|
================================================================================
|
||
|
|
|
||
|
|
For all platforms, unpack into a clean (new) directory. Installing on top of
|
||
|
|
previously released builds may cause problems with Firefox.
|
||
|
|
|
||
|
|
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-os2-*.zip where the "*" is replaced by the 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, i.e.
|
||
|
|
unzip firefox-os2-1.0.1.zip -d c:\firefox-1.0.1
|
||
|
|
will unpack Firefox into c:\firefox-1.0.1\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, make sure that the C library DLLs are copied to the
|
||
|
|
installation directory or installed in the LIBPATH, and then double-click
|
||
|
|
the Firefox.exe object.
|
||
|
|
|
||
|
|
|
||
|
|
Running multiple versions concurrently
|
||
|
|
--------------------------------------
|
||
|
|
|
||
|
|
Because various members of the Mozilla family (i.e. 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
|
||
|
|
exists 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 different versions of Firefox
|
||
|
|
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/cgi-bin/h-search?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 MOZILLA_USE_EXTENDED_FT2LIB=T
|
||
|
|
If you have the Innotek Font Engine installed this variable enables special
|
||
|
|
functions in Firefox to handle unicode characters.
|
||
|
|
|
||
|
|
- set MOZ_NO_REMOTE=1
|
||
|
|
Use this to run two instances of Firefox simultaneously (like e.g. debug
|
||
|
|
and optimized version).

Known Problems of the OS/2 version
|
||
|
|
----------------------------------
|
||
|
|
|
||
|
|
Cross-platform problems are usually listed in the release notes of each
|
||
|
|
milestone release.
|
||
|
|
|
||
|
|
- Bug 167884, "100% CPU load when viewing site [tiling transparent PNG]":
|
||
|
|
https://bugzilla.mozilla.org/show_bug.cgi?id=167884
|
||
|
|
On OS/2, Mozilla's rendering engine is known to have very slow performance on
|
||
|
|
websites that use small, repeated images with transparency for their layout.
|
||
|
|
This affects rendering in Firefox as well.
|
||
|
|
|
||
|
|
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/>.
