Firefox already uses bsdiff to generate binary diffs for update distribution. Courgette looks like a promising way to shrink those updates even further. (Details in the discussion linked from: https://bugzilla.mozilla.org/show_bug.cgi?id=504624 https://bugzilla.mozilla.org/show_bug.cgi?id=504624) I can't find a reference, but I think the "one billion" count only counts full downloads; updates installed via "Check for updates" aren't included in the count.
