Frost Giants are... diplomatic. Most of the time, if they're on Niflheimr. [She's never had any quarrel with them, past Ragnarök. Then again, they hadn't sided with Loki. Before? She'd had her fair share of battles with them.] But Fire and Rock Giants have foul tempers, and they don't like humans very much. Or anything human-shaped. They dislike Asgardians even more.
