I'm adding a perf test that measures the time from process start to the Fenix Home Activity.
However when launching Fenix through perftest and Browsertime, `geckodriver::marionette` is unable to connect to the android browser:
```

I'm adding a perf test that measures the time from process start to the Fenix Home Activity.
However when launching Fenix through perftest and Browsertime, `geckodriver::marionette` connects to the android browser, however it does not proceed from there.
```

```
And on the adb side:
