Instead of having the `localStorage` data being accessed
from different locations, all accesses are now funnelled
to the main process.
Doing so simplifies the code in auxiliary processes and
also remove the need for browser.storage.local.onChanged()
listeners.
No longer using an onChanged() listener also happens to
remove spurious warnings from the Firefox console.
