Bug 1411517 - stylo: "layout.css.stylo-blocklist.enabled" pref's default value should be false.
At present, the "layout.css.stylo-blocklist.blocked_domains" pref is empty. It
is probably meaningless to set "layout.css.stylo-blocklist.enabled" pref to true
by default. We can set "layout.css.stylo-blocklist.enabled" pref to true by the
styloblocklist system add-on once the "layout.css.stylo-blocklist.blocked_domains"
pref is non-empty.
