Hi Emilio, could you please take a look? It racked up 60 failures in 2 days

Yes, I'm looking, but I haven't been able to reproduce this... Valentin, are you familiar with about:cache? It seems we're not finding the right data in about:cache-entry...

I think there might be a race where the data ends up in the first rather than the second cache entry... But un the interim disabling that specific assertion doesn't seem like the worst path forward? It's not testing much.

This passed when run in confirm failure mode (rerun the test 4x in the same session).

This indicates that the test is probably a lower frequency intermittent and harder to reproduce/debug.
