aairey/firefox-sslv3 repository overview

⁠firefox-sslv3

Docker image which runs a Firefox version that still supports the deprecated protocol SSLv3.
Very handy to access those few legacy web applications that can't be updated for whatever reason.

⁠Tags

• latest: same as centos, it is the smallest image
• debian: built on debian:8
• centos: built on centos:7

⁠Prerequisites

⁠Docker host setup

First on your linux docker host, you must enable the container to use the X Server:

xhost local:root

⁠SELinux

If your docker host is SELinux enabled (for example Fedora/CentOS are by default), there is a SELinux Policy included on the GitHub repo⁠ which you can import on your system.

This policy allows containers to connect to the X11 Unix Socket on your Docker host.
To import it:

semodule -i mypol.pp

⁠Using

Then run the containter as follows:

docker run -ti --rm \
           -e DISPLAY=$DISPLAY \
           -v /tmp/.X11-unix:/tmp/.X11-unix:z \
           aairey/firefox-sslv3

And a Firefox v33 should pop up.

To browse to a website directly from the CLI:

docker run -ti --rm \
           -e DISPLAY=$DISPLAY \
           -v /tmp/.X11-unix:/tmp/.X11-unix:z \
           aairey/firefox-sslv3 \
