Error after running a test using the Firefox browser on the CLI in Windows.

[Lorenzras]

Current behavior

Using the commandline, test itself succeeds but throws the following error.

[firefox-profile] cannot delete profileDir on exit

Here is what we did so far to no avail.

1. Delete node_modules, then reinstall packages.
2. Clone the test repository on a different Windows computer.

Desired behavior

No response

Other

There was no problem running on Mac or in GUI mode.

In your screenshot Windows is showing an issue because the resource is busy. You may want to reboot your system and see if that clears the issue.
