# "Why isn't utils.js a JavaScript module that's imported into the other files
# that need its functions?" you ask? Because when it is, then whenever the
# extension is updated in a running Chrome instance, utils.js starts failing
# to import with the error "Failed to fetch dynamically imported module." I
# spent hours banging my head against this trying to figure out what's causing
# it and how to fix it and eventually gave up. The path of least resistence is
# to just embed a copy of the code in all the files that need it.
