zip版的firefox 1.5b2 装不上

解压后点firefox.exe跳出来个窗口几秒后消失，就象是Dos版，readme说好象是要下个libc-0.5.1.exe放在firefox目录下(看不太明白）可还是无法运行，请问zip版的怎么用？

zip版的本身就不用安装，解压缩后就可以使用。
libc－libc-0.5.1.exe是什么东东，第一次听说。

看看你的系统进程里有没有Firefox的身影

我是在这下的，下面的readme没看明白怎么做

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/>.
