Understanding Browser Storage
localStorage
Persists indefinitely across browser sessions until explicitly cleared — commonly used for user preferences and cached data.
sessionStorage
Cleared automatically when the browser tab closes — often used for temporary form state or wizard steps.
Cookies
Sent with every HTTP request to the same origin, commonly used for session identifiers and tracking.
Origin-Isolated
Browsers strictly isolate storage per-origin — this tool can only ever see this page's own data.
A Note on HttpOnly Cookies
JavaScript — and therefore this tool — cannot read cookies marked HttpOnly, which is precisely the point of that flag: it prevents client-side scripts (including malicious ones injected via XSS) from stealing sensitive session cookies. If you don't see an expected cookie listed here, it's likely protected this way, which is a good security sign, not a bug.
Key Takeaways
- Three Storage Types: View localStorage, sessionStorage, and accessible cookies side by side.
- This Page Only: Origin isolation means only ronaldreeves.com's own storage is visible.
- Client-Side Only: Nothing is transmitted — this is a live, local read of your own browser.
