[🐛 Bug]: Firefox driver fails when used in Selenium Grid

[ablok]

What happened?

When I run a very simple test locally against Chrome, Edge and Firefox, the test passes without any issue. However, if I run the same test against a Selenium Docker grid, the Firefox test seems to fail.
I created a sample project here: https://github.com/ablok/selenium-firefox-issue

Command used to start Selenium Grid with Docker (or Kubernetes)

See sample project: https://github.com/ablok/selenium-firefox-issue

Relevant log output

This is the stacktrace I see:

Can you share the Grid logs, please?

@diemol I did add the docker logs yesterday. Is this what you are looking for? Or do you need more?

Via logs, I saw a few messages that looks confused

I haven't had time to check this, @ablok

browserleftoverscleanup

I think we need to change the configuration so it does not restart unless it is enabled.
