[Dnssec-trigger] persistent cache needed?

After booting up and re-opening Firefox, restoring 50-100 tabs causes
so much DNS traffic that unbound goes unresponsive, and queries
repeatedly timeout for many minutes until things finally settle down.
I thought Firefox's behavior was to not reload every tab until you
activate the tab, but maybe it is still doing DNS pre-fetches for the
inactive tabs? I don't know.
I think we need a persistent cache, saved across restarts/reboots.
What else can we do to solve this problem?
Or is the verbosity the cause of the problem:
#journalctl -b -u unbound | wc -l
# verbosity number, 0 is least verbose. 1 is default.
