> I made sure to check all the headers in the original message, and everything looked correct Headers are a bad heuristic for discerning sketchy emails I've found, since they're a garbled mess & hard to make sense of without some specialized tool, and clearly Gmail doesn't understand the headers either and had a false positive. I imagine because the from address being `accounts@firefox.com` probably raised some flags since there's obviously some ongoing phishing campaign to takeover Firefox accounts, that you're unaware of, until now.
