Through the years we had different problems running Firefox on Android phones. Let's verify that it works fine with the latest release so we can prepare running the tests.
I've had problem being able to get X amount of runs on Firefox to actually work. There's a upstream bug for what I've seen: Ihttps://github.com/mozilla/geckodriver/issues/2157

Running from the Raspberry Pi, running 11 runs, one or two of the runs get ERROR: WebDriverError: Failed to decode response from marionette. To get some more useful out of that I need to turn on the Geckodriver log.
The full trace log looks like this:

This also is reproducible using my desktop computer running tests on the same phone.
I reported this earlier this year in: https://github.com/mozilla/geckodriver/issues/2157 - I'll ping that issue and see if there's another way than rebuild Geckodriver and add extra travelogs that can helps them.
Running with Moto G5 I don't get any failures at all, this happens only with Samsung A51.
