SuperLogout, one-click sign out from popular sites
How it works: we load each site's logout URL as a hidden image. Sites with CSRF protection (most modern ones) won't honor this, use the open link to sign out manually. Open this page in the browser profile you want to log out of.
Evercookie persistence test
Inspired by Samy Kamkar's Evercookie: plants the same identifier in every browser storage mechanism, so if any one survives a clear cookies the tracker can resurrect the others. Plant the ID, then clear cookies in your browser, anything still showing here is an evercookie vector.
| Mechanism | Stored value | Status |
|---|
localStorage
No localStorage entries.
sessionStorage
No sessionStorage entries.
Cookies set by other sites are isolated by the same-origin policy, JavaScript on cannot read them. To wipe everything in one go, use your browser's Clear browsing data (Ctrl/Cmd + Shift + Delete).
