It is highly recommended for you to keep this toggled on. If you disable JavaScript, in some cases you will not be able to use certain features on a website while other websites might break completely or you will be stuck using a very old version of the page. If you don’t want to get any notifications try using Incognito mode. With the default setting, Chrome will alert you when a site, application, or extension wishes to notify you. With the default setting, the feature is allowed for sites, but it is recommended to toggle this off in order to protect your privacy. Some websites will access your device’s motion-sensing features (light or proximity sensors).
To let the site know where you are, choose Allow.
