How to run an old Firefox browser in Docker Ubuntu with VNC

gistfile1.txt

```
docker run -p 6080:80 -v /dev/shm:/dev/shm dorowu/ubuntu-desktop-lxde-vnc
```

Browse to http://127.0.0.1:6080/

In the VNC UI, run the LXTerminal. Paste these commands to install a given version of Firefox. Set `FF_VERS` to the release you want. See available releases at http://releases.mozilla.org/pub/firefox/releases

```
apt-get update && apt-get install wget
FF_VERS=60.6.3esr
FF_INST=/firefox/$FF_VERS
FF_URL=http://releases.mozilla.org/pub/firefox/releases/$FF_VERS/linux-x86_64/en-US/firefox-$FF_VERS.tar.bz2
mkdir -p $FF_INST
wget -qO- $FF_URL | tar xvj --strip 1 -C $FF_INST/
$FF_INST/firefox
# Optionally link this install as the default FF install:
# ln -s "$FF_INST/firefox" /usr/bin/firefox
```

If you have trouble pasting the commands into the Terminal, first launch the Leafpad accessory and try copy/pasting in there first. Then use the Edit menu to copy/paste within apps. You might also try pasting the commands into the novnc clipboard toolbar flyout before pasting into Leafpad.

Nice!, it works! +1
very useful for access to old UI hardware still using old TLS 1.0
