Browser Settings

Check whether JavaScript, cookies and local storage are switched on, the settings almost every modern website depends on.

  • JavaScript

    Detecting…

    Whether JavaScript runs in your browser. Almost every modern website needs it for menus, forms and interactive features.

  • Cookies

    Detecting…

    Whether your browser accepts cookies from the site you are visiting, which websites need to keep you signed in.

  • Local storage

    Detecting…

    Whether websites can save data such as settings and drafts in your browser's local storage.

Most websites rely on a few browser settings to work properly: JavaScript runs their interface, cookies keep you signed in and local storage remembers your preferences. These checks show whether each one is switched on in your browser right now. Every test runs in your browser and nothing is sent to our servers.

The checks

  • JavaScript: whether scripts run, which almost every modern site needs.
  • Cookies: whether sites can keep you signed in.
  • Local storage: whether sites can remember your settings and drafts.

Why a setting might be off

  • it was switched off in your browser, by you or by your organization’s IT policy
  • a privacy, script-blocking or ad-blocking extension blocks it
  • your browser’s strict privacy protection blocks storage for some sites

The JavaScript and cookie checks also explain how to switch them back on in Chrome, Safari, Firefox and Edge.

When these checks are useful

  • finding out why a site won’t load, won’t keep you signed in or forgets your choices
  • confirming a setting works after you changed it
  • telling a support team which features your browser allows
