This is happening to me both for the version on the Chrome app store as well as when I cloned and installed it locally

window.localStorage is actually null

Chrome version: Version 88.0.4324.150 (Official Build) (x86_64)

I hacked it locally to use chrome.storage.local.get() and chrome.storage.local.set().

Not really in a position to submit a PR because I can't oversee race conditions (API turns from sync to async) and cross-browser concerns.
