FireFox 4

If you just download the firefox tar, then you’ll get an error:

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


./firefox-bin: /usr/lib/ version `GLIBCXX_3.4.9' not found (required by /home/cameron/firefox/

To fix this follow these steps.

cd ~
download the file: firefox-4.0.tar.bz2
tar xvf firefox-4.0.tar.bz2
cd firefox
download the fedora rpm: libstdc++
rpm2cpio libstdc++-4.3.0-8.i386.rpm | cpio -i --make-directories
#note the lack of / at front of usr/lib in the line below
mv usr/lib/* .
rmdir usr/lib usr

hope that helps..

    Thanks Cameron!.This helped me to move a bit for getting firefox 4 on CentOS 5.5 working.

    1)Downloaded firefox and unzipped and then untarred it. 
    2)downloaded libstdc++-4.3.0-8.x86_64.rpm at /home/dev/Desktop. Then switched to root
    3)rpm2cpio libstdc++-4.3.0-8.i386.rpm | cpio -i –make-directories
    4)mv usr/lib/* .

    This is telling me
    mv: cannot stat `usr/lib/*’: No such file or directory
    However, i ran above command with /usr
    will that break anything :-O

    by rmdir usr/lib usr

    are you trying to delete /usr/lib

  2. cameron says:* is from the downloaded rpm .. when you rpm2cpio it, you are unbundling it .. it will have this file in usr/lib dir … so for you

    There are two files .. if there aren’t then run the rpm2cpio command again.

    yes the /usr/lib dir will break things.

    hope that helps.

    Thanks for the post, so much time saved versus trying to build firefox!

  4. sam says:

    Thanks ,, this certainly helped me …

    Initially on my system firefox was getting stalled. with following message

    version `GLIBCXX_3.4.9′ not found (required by /usr/local/firefox/
    [ NOTE : this too after unpacking libstdc++-4.3.0-8.i386.rpm with cpio and linking with

    One thing that I have done along with performing above said steps is —
    I have put one soft link of new libstdc++ lib at home dir of firefox.

    And that has solved my problem.

  5. cameron says:

    yeah , I don’ t know why LD_LIBRARY_PATH doesn’t work, but it doesn’t.

    sym link also works! Actually, that might make the instructions more clear (and less dangerous!)


  6. Saghalie says:

    Worked like a charm! Thanks so much.

    One issue that I did run in to though was the
    rpm2cpio libstdc++-4.3.0-8.i386.rpm | cpio -i –make-directories

    I had to change it to read
    rpm2cpio libstdc++-4.3.0-8.i386.rpm | cpio -i -–make-directories
    in order for it to work.



  7. pavi says:

    it’s working fine, thanks a lot.

    I have faced the same issue like Saghelie, thanks for spoting it.

  8. Manuel says:

    Thank you Cameron for this simple & fully functional guide. I just added a few steps:
    (as root user)

    # cd ..
    # # Move the recently unzipped firefox directory
    # mv firefox /usr/local/lib/firefox-4.0
    # cd /usr/bin
    # mv firefox firefox-3
    # ln /usr/local/lib/firefox-4.0/firefox .

    This will allow you to execute firefox 4 by clicking your (old) desktop icons or application launchers.

  9. Abid says:

    I have tried each step but at the end
    rmdir usr/lib usr is giving me some problem
    it says usr directory is not empty .
    So what i have to do ?? please help

  10. Abid says:

    Finally Cracked it 🙂 Thanks a lot

  11. cameron says:

    great. If the instructions were not correct, please let me know. Or even perhaps where I should highlight something to make it clearer!


  12. Juan Martinez says:

    It works, but firefox-4.0.1 produces error reporting agent
    when I close firefox window.

    It always produces this agent.

  13. Juan Martinez says:

    The false thing is as follows.

    If I close firefox 4 window, it ALWAYS produces
    Mozilla Error Report Agent.
    We need to examine it.

  14. krishna says:

    Thanks… it helped me to bring up without big hazzles.

    Initially when copied pasted directly the following command , it was not working

    “rpm2cpio libstdc++-4.3.0-8.i386.rpm | cpio -i -–make-directories” , since the –make-directories came up as single big – (some other symbol) on my terminal.

    Later replaced it with — and found working

  15. krishna says:

    I think it is browser issue , please replace — with two -‘s

  16. cameron says:

    thanks krishna, hopefully the new font is better.

  17. reece says:

    Can I help with this please?

    When I do this step: mv usr/lib/*

    I get this: mv: `usr/lib/′ and `usr/lib/′ are the same file

    Am I missing something here? I’m a complete noob, are there any other steps or something else I need to add to your commands? where do I move what to?

    I tried this and overwrote : mv usr/lib/ /usr/lib/

    Is it broken now?

  18. reece says:

    ^Sorry I meant can I GET help please 😉

  19. cameron says:

    reece, you need the . at the end, it means copy to the current directory (so you have to be in the correct directory)

  20. ben says:

    Thanks for the tip!
    It works even for firefox 5.0.1

  21. Praveen says:

    Hi Cameron,

    I need logo generator script. Is something for sale ? Or do you have any API access for that ? Much appreciated your help. Kindly get back to me. Thanks

    I replied in a few other places. Let me know if you still have any questions (but the contact form/email is better) – Cameron
