The cookies test failed. How do I enable cookies?

In Chrome: Settings → Privacy and security → Third-party cookies. In Firefox: Settings → Privacy & Security. Allow cookies at least for the sites you use, then reload this page.

Should I block third-party cookies?

Usually yes. First-party cookies keep you logged in to the site you're on; third-party cookies mostly serve cross-site tracking. Most browsers now block third-party cookies by default.

Why do cookies work in normal mode but not private mode?

Private/incognito windows accept cookies but delete them when the window closes, and often block third-party cookies more aggressively. That's expected behavior, not a fault.

Cookies failing? Here's what it breaks

With cookies blocked you can't stay logged in, shopping carts empty themselves, and many sites show a repeated cookie banner. The panel above also tests localStorage and IndexedDB, which modern sites use alongside cookies.
