Firefox on Moto G5 have 0 visual metrics for https://www.wikipedia.org
Something is broken when you run default settings for Firefox (130) on a Moto G5. I've verified this on my Mac and a Raspberry Pi with a Moto G5 connected.
I've tested in using sitespeed.io but should be the same in browsertime:
bin/sitespeed.js https://www.wikipedia.org -n 1 -o --android --video --visualMetrics -b firefox

When test using Chrome it works.
I can only reoproduce this when testing https://www.wikipedia.org. If I change the pageCompleteCheck to listen for networks activity, the metrics are correct. Maybe the test/video ends too early? Yes tit does.

By default we should wait for the loadEventEnd + 2 seconds but it seems like something changed in Firefox?
Hmm, I cannot reproduce this running through Browsertime, that is strange.
