[🐛 Bug]: Firefox Blank or White Screen in OpenShift Container Platform when runnung exeutions

[varsha-rav]

What happened?

Hi, We've set up selenium 4 hub along with selenium/node-firefox, selenium/node-chrome and selenium/node-edge. On running executions on selenium/node-firefox, we're noticing a blank screen as below

The below issue shows that adding allowPrivilegeEscalation: true is the fix but we have limited privileges in client environment and this permission is not allowed https://github.com/SeleniumHQ/docker-selenium/issues/1786

Is there any alternative to fix this issue or any update on this bug?

PS: Executions on edge and chrome are working as expected
