Firefox 3.6 under debian squeeze

While I want to start my Firefox 3.6 which I installed under /opt/firefox/

I have the Following Error:

[root@box]: ./firefox-bin 
./firefox-bin: error while loading shared libraries: libxul.so: cannot open shared object file: No such file or directory

Here is my ldd output:

ldd firefox-bin
        linux-gate.so.1 =>  (0xf77cf000)
        libpthread.so.0 => /lib32/libpthread.so.0 (0xf779e000)
        libxul.so => not found
        libxpcom.so => not found
        libmozalloc.so => not found
        libplds4.so => /usr/lib32/libplds4.so (0xf779a000)
        libplc4.so => /usr/lib32/libplc4.so (0xf7796000)
        llibnspr4.so => /usr/lib32/libnspr4.so (0xf7762000)

        libstdc++.so.6 => /usr/lib32/libstdc++.so.6 (0xf开发者_Go百科7668000)

        libgcc_s.so.1 => /usr/lib32/libgcc_s.so.1 (0xf7624000)
        libc.so.6 => /lib32/libc.so.6 (0xf74dd000)
        /lib/ld-linux.so.2 (0xf77d0000)

The file is there an all the others too:

[root@box]: locate libxul   
 /opt/firefox/libxul.so

So they are 3 files missing. Can you help to get me them?

EDIT:

With the short fix:

export LD_LIBRARY_PATH=/opt/firefox/

I get the same error with ./firefox-bin

./firefox-bin: error while loading shared libraries: libpangoft2-1.0.so.0: cannot open shared object file: No such file or directory

You should start it with /opt/firefox/firefox

Looks like there is something wrong with you package mananger ...

ldd firefox-bin
    libxul.so => not found
    ...
locate libxul
     /opt/firefox/libxul.so

this part can be solved with

export LD_LIBRARY_PATH=/opt/firefox/
..../firefox-bin

or

LD_LIBRARY_PATH=/opt/firefox/ ..../firefox-bin

Try:

    sudo apt-get install ia32-libs-gtk
