We found that this problem only happen for us when we run the container with a non-root user. Our solving steps were as follows:

First, we changed the container to run as root. This failed with firefox not being identified on the system.
This is the problem reported on #85, but the problem is not running as root per se, actually firefox only blocks running as a user that does not own the $HOME path.

Second, we removed our $HOME var and passed the full firefox path to cypress (--browser /opt/firefox/firefox). This works, but all artifacts generated are now own by the root user.

Third, we added a script to run at the end of the test suite that chowns the artifacts back to the correct user.

Those steps are only necessary for Firefox due to it's security restriction.

Hope this helps everyone else that reaches a similar problem

The error message output by Firefox 117 in a similar situation running on GitHub is:

"Running Firefox as root in a regular user's session is not supported. ($HOME is /github/home which is owned by uid 1001.)"

Advice to avoid this error is now included in the README.

Perhaps this issue could be closed now?
