Retrieving Firefox browser console logs

[mwsessom]

I am trying to retrieve the browser console logs from Firefox. I'm able to do this with the Chrome container but have been unsuccessful using the Firefox container.

Firefox offers a couple preferences to redirect console logs to stdout devtools.console.stdout.content and devtools.console.stdout.chrome. However, I don't believe the Firefox container is capturing the stdout from Firefox.

Is there a way to capture stdout coming from the Firefox browser? Maybe there's a way to redirect the output to a file? The only output coming from the docker run ... cmd seems to be the Selenium log.
