summary: I must run a firefox-3.x to telework, and I run debian at home. I previously had firefox-3.6.28 installed and running on an up-to-date debian, but mistakenly destroyed that install. I have reinstalled the OS, and reinstalled firefox-3.6.28, but it will not run:

$ /usr/local/share/firefox-3.6.28/firefox -no-remote -ProfileManager &
> [1] 8297
> $ /usr/local/share/firefox-3.6.28/run-mozilla.sh: 143: exec: /usr/local/share/firefox-3.6.28/firefox-bin: not found

details:

As detailed in a previous question

https://support.mozilla.org/en-US/questions/931873

my workplace forces me to run a firefox-3.x in order to install a plugin (F5NAP) that provides remote access. (While the question above suggests that a firefox-8.x would also be an option, the latter is not in fact compatible with my workplace's servers' configuration.) I previously was able to do this first ~2 years ago, as indicated in the question above, on a 64-bit PC with debian=wheezy/sid (distro=LMDE==Linux Mint Debian Edition).

About a month ago, that older PC developed severe problems, so I began to setup a newer PC, which must also run the VPN, and therefore firefox-3.6.28+F5NAP. The new box is running

$ uname -a
Linux box 3.11-2-amd64 #1 SMP Debian 3.11.8-1 (2013-11-13) x86_64 GNU/Linux
$ lsb_release -a
No LSB modules are available.
Distributor ID: LinuxMint
Description:    LMDE Cinnamon Edition
Release:        1
Codename:       debian
$ cat /etc/debian_version
jessie/sid

Note that the new box is also 64-bit, but (unlike the old box) is running the latest debian with multiarch support

https://wiki.debian.org/Multiarch

(whereas the old box used package=ia32-libs). I was able to install firefox-3.6.28+F5NAP on the new box as detailed here

http://forums.linuxmint.com/viewtopic.php?f=190&t=164522

Unfortunately I later misconfigured LVM, forcing me to reinstall everything :-( I have LMDE and most applications installed (from APT, with packages currently up-to-date) and everything appears to work (particularly the firefox-28.0 which I am using to ask this question). However this time I'm getting a very different error when I run firefox-3.6.28.

I'm installing and running firefox-3.6.28 with the following bash scriptlet (which is how I installed it previously):

FF_VERSION='3.6.28'
LINUX_VERSION='i686' # since there is no 64-bit build of this version of firefox
EXEC_FN='firefox'
LANG='en-US'
FF_WITH_VERSION="firefox-${FF_VERSION}"
URI="https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/${FF_VERSION}/linux-${LINUX_VERSION}/${LANG}/${FF_WITH_VERSION}.tar.bz2"
BUILD_DIR="/tmp/${FF_WITH_VERSION}"
UNZIP_DIR="${BUILD_DIR}/firefox"
INSTALL_ROOT='/usr/local/share'
INSTALL_OWN='root:staff' # like peers on new LMDE, not 'root:root'
INSTALL_DIR="${INSTALL_ROOT}/${FF_WITH_VERSION}"
EXEC_FP="${INSTALL_DIR}/${EXEC_FN}"
EXEC_ARGS='-no-remote -ProfileManager'

# `tar j` == bzip2
for CMD in \
  "mkdir -p ${BUILD_DIR}" \
  "sudo mkdir -p ${INSTALL_ROOT}" \
  "pushd ${BUILD_DIR}" \
  "wget -O - ${URI} | tar xfj -" \
  "find | wc -l" \
  "popd" \
  "sudo mv ${UNZIP_DIR} ${INSTALL_DIR}" \
  "sudo chown -R ${INSTALL_OWN} ${INSTALL_DIR}/" \
  "du -hs ${INSTALL_DIR}/" \
  "ls -alh ${EXEC_FP}" \
  "${EXEC_FP} ${EXEC_ARGS} &" \
; do
  echo -e "$ ${CMD}"
  eval "${CMD}"
done

firefox-3.6.28 appears to install correctly:

If not: how to fix, or further debug, this problem?

Your prompt assistance is appreciated, since I can't telework until I get this fixed :-(

As you may know it was not until Firefox 4.0 that there has been 64-bit Linux Releases of Firefox from Mozilla. Some Linux distros may have built 64-bit Firefox packages before then.

Also note you do not need to use the -no-remote switch when starting with -P or -ProfileManager unless you were trying to say run a secend instance.

@james: "Some Linux distros may have built 64-bit Firefox packages before then."

Alas, I have not seen any 64-bit firefox-3.x for debian.

@james: "you do not need to use the -no-remote switch when starting with -P or -ProfileManager unless you were trying to say run a secend instance."

Correct, but I am trying to run a second instance. I typically run latest available packaged firefox (which for LMDE currently is version=29) for all purposes except the F5NAP (which does not support it). When I need to VPN, I run as separate second instance of firefox-3.6.28+F5NAP (on a separate profile) for the duration of the session. Fortunately the two firefoxes "play well together" as long as they use separate profiles, and as long as the profile for firefox-3.6.28+F5NAP is configured to not auto-update.
