Firefox Nodes from selenium are working perfect in openshift.

In Openshift everything needs special permissions for example xvfb

https://docs.openshift.com/container-platform/4.15/openshift_images/create-images.html#use-uid_create-images
The container runs on the group 0, so every folder needs that permission.

RUN chgrp -R 0 /some/directory && \
    chmod -R g=u /some/directory

Cypress now works in Openshift.
