Firefox's zero-day flaw was used to attack Coinbase employees

Coinbase's exchange and wallet service was attacked using Firefox’s zero-day security flaw, according to a recent tweet from Coinbase security researcher Philip Martin. In fact, Martin found that there were two separate Firefox zero-day attacks. Martin tweeted:

On Monday, Coinbase detected & blocked an attempt by an attacker to leverage the reported 0-day, along with a separate 0-day firefox sandbox escape, to target Coinbase employees.
