I promised a proposal:
navigator.mozSettings.get('locale.hour12').then(value => {
console.log('value for locale.hour12 is: ' + value);
});This would be asynchronous, and only available for a small set of variables (whitelisted). zb. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
