Something is clearly wrong here:
14:15:53 INFO - PID 10836 | 1551881753678 mozrunner::runner INFO Running command: "Z:\task_1551879826\build\application\firefox\firefox.exe" "-marionette" "-foreground" "-no-remote" "-profile" "C:\Users\task_1551879826\AppData\Local\Temp\rust_mozprofile.ZlvugkK1i6M5"

We start Firefox and 1s later we already kill the process. I wonder under which conditions this can happen. The relevant code is at least here:
If we would hit Some in the first if block I would expect to see output with the exit status. But given that this is not visible, the process is there but maybe Firefox doesn't start?
I could only explain the early return here with some weird behavior in now.elapsed(), and that it returns a value which is already larger than the timeout.
Andreas, do you have an idea?

“permission denied” usually indicates the inability to launch a
program when it is not executable. This is rare case where I think
I a Rust backtrace would be useful. If you can run the test
prepending RUST_BACKTRACE=1 that would give us a better indication
what exactly goes wrong, where.

I cannot. It is a very rare case and so far only happened a handfull of times. The only option I could see is to add the env variable by default by the marionette executor when running wdspec tests.
James would that be fine with you?
