Of those three, I only _have_ the first one (GracePeriod), which is
currently at its default of 2592000; has the unit of measure changed at
some point (Firefox version)?

What do the three things mean? (Provided it "runs down" in a reasonable
period, say a minute or few, I can't see a problem with caching DNS
data: prefetch, indeed, could be not a good idea. I have _that_ one
turned off [...disablePrefetch set to true].)
