Cookie Injector

Cookie Injector by MultiLab manages website cookies and saved sessions for development and testing. Save cookies and optional localStorage, organize sessions in workspaces, compare changes, and restore backup snapshots. Import and export Chrome JSON, Playwright storageState, Puppeteer cookies, Netscape and native packages. Export a selected website or all cookies in the current Chrome profile. Password-protected exports use local AES-256-GCM encryption. Test clean visitors, consent resets, saved roles and temporary sessions. Preview domain/origin changes when transferring a set between test environments. Use local WebRTC checks, external IP checks on request, and links to third-party diagnostic websites. The interface is available in English and Russian, in a compact popup or full management page. ACCESS The first seven days are a free trial without a key. Continued use of the main functions requires an activated, unexpired MultiLab key. Exporting saved data and restoring snapshots remain available after the trial. To activate immediately, open the three-dot menu and select “Activate with a key”. For key purchases, contact https://t.me/MultiLabSupport. The extension does not collect payments or make automatic charges. PRIVACY Sessions, snapshots and diagnostic history remain in this Chrome profile. Website cookies and localStorage are not sent to our server. For activation and periodic verification, the MultiLab key is sent over HTTPS to tonanza.ru; the server receives the key and network request, including the IP address. External IP requests run only when selected. External diagnostic websites use their own privacy policies. The local library and ordinary exports are not encrypted by the extension. Password protection applies only to encrypted export packages. Cookies and localStorage can contain active session tokens and personal data. LIMITATIONS localStorage requires an open tab for that website. Saved sessions do not create separate browser profiles. IndexedDB, sessionStorage, browser fingerprints and proxy settings are not transferred. Restoring cookies does not guarantee website sign-in; diagnostics do not guarantee anonymity.
