You can check with wireshark, most javascript based crypto miners are blocked these days now tho, it was a temporary trend which wasn't appreciated as it was often too stealthy and misused. It's also pretty much only Monero that was ever mined that way, maybe some other ASIC resistant coins too.
Filter by DNS in wireshark and search for "xmr" or similar domains. Tho most likely just crappy code or generic spyware not detected by pi-hole.
Never thought of anti-crypto miner extensions, sounds shady. uBlock origin should do the trick, tho I would have expected pi-hole having most of those miners on it's block list by now. I think the service is coin-hive something, they changed their domain a lot to evade ban.
Seems like they released it as open source now: https://github.com/cazala/coin-hive, if that project is the javascript miner, it could be on any domain and very hard to block. Gonna have to dig deeper into that.
