Default Unbound problems

Greetings all,

I have been experimenting with installing unbound on my laptop, connected to a router via an Ethernet interface.

1. My fist problem is that after issuing several pings, I notice an error:

fail: the anchor is NOT ok and could not be fixed"

rm /var/unbound/db/root.key
unbound-anchor -a /var/unbound/db/root.key
unbound-anchor -F
restore the root.key, but in a while the same problem reoccurs.

Although based on my search some people do have similar root.key problem, it appears to be on the order of months and not minutes. Any ideas how to resolve the problem would be appreciated.

2. Although the response to the first ping takes a while, which I attribute to use of root server(s), the subsequent ping responses do not appear to be any faster. This puzzles me because my understanding is that unbound should cache the response. Do I have an error in the unbound.conf?

3. I cannot figure out from the various unbound related web pages, how to configure a browser (Firefox) to use the server. Do I need some redirection rule in pf.conf?
