This needs to be included conditionally - this file will be used on all kind of
platforms, the filterHits module is currently Firefox-only however. I guess
something like that:

let FilterHits = null;
try
{
  ({FilterHits} = require("filterHits"));
}
catch (e) {}

You can then use it conditionally below.
