// This is supposed to be all google search sites. Copied from faviconizegoogle.user.js
// But then I also added /url pages, to catch "Redirect Notice"s

// TODO This currently acts on pages which do not support lucky search (e.g. Google Images). Ideally we would activate only on pages where we can actually help!
