  1. FYI, the extract command won’t work as written. Since the archive is compressed with bzip, the correct extraction options would be `tar jxvf firefox-version.tar.bz2`

  2. Big thanks for such a detailed instruction. I did not like version 23, this was great to go back to a previous version. Be sure to block future updates. I used about:config, as I was not sure the UI worked.

  3. I have upgrade my ubuntu to 14.04 and trying to install previous verion of firefox 20.0 with following same steps but i am not able to start firefox after this clicking but not opening…?? any permission issue…

  4. I attempt to install version 9.0, 12.0, 12.0 on kubuntu 14.10. But not working. When I start the firefox then open the crash report window.

  5. None of these commands worked for me! Running Ubuntu 12.04LTS & FF 36.1 trying to downgrade to FF 18.0.2 Every peace of info I’ve tried from here to the Ubuntu forum have all been a joke!
    Nothing but mis-information everywhere!

  6. Hello Everyone,

    I tried to downgrade Firefox 28 to 26 in Ubintu 14.04 LTS, but it rejects overwriting the directory

    mv: cannot overwrite non-directory ‘/opt/firefox26/firefox’ with directory ‘firefox/’

    Could anyone say, why it is so and what should I do?

    I would appreciate detailed command as I am not a programming expert.

    Many thanks for your help.
    Cheers,
    Natalia
