FireFox is getting on board with an iniative already set forth by Chrome Browser, and that is to stop hackers from using your computer for unauthorized crypto-mining. Mozilla did also tell Bleeping Computer that it was doing some domain level blocking of cryptojackers that it had not previously publicly identified.

This "exploring" on the part of Mozilla could mean one of two things. The first would be if Firefox would start throttling JavaScript "workers" executed in background tabs, similar to the method the Chrome team recently took to deal with cryptojackers.
