Hi, You don't say how much sunlight they are getting. In general, when plants get tall and leggy and fall over, it's a sign they aren't getting enough sunlight. Also, foxgloves generally don't rebloom after their main flowering period. Remember, foxgloves are biennials so each plant only lives for two years (blooming in their second year). They often look like they are perennials because they appear in the same spot all the time, but they resow themselves easily so it looks like the same plants year after year.
