Multisession - Isolated Browser Sessions | Multi-Account Manager

20 isolated browser sessions for multiple accounts. Switch profiles with separate cookies, storage, IndexedDB and fingerprint.

Run up to 20 isolated browser sessions in one Chrome window. Multisession by htmlrunner is a multi-account manager and session switcher designed for isolated browser profiles, session management, and privacy-focused browsing workflows. Developed by htmlrunner, Multisession gives every profile its own cookies, localStorage, sessionStorage, IndexedDB, and fingerprint settings. Switch between profiles with one click without opening additional Chrome windows or using incognito mode. Multisession is useful for managing separate personal and work profiles, testing different website accounts, e-commerce workflows, client projects, QA testing environments, and web development. WHY MULTISESSION * Up to 20 isolated browser sessions * Per-profile cookie, localStorage, and IndexedDB isolation * Fingerprint protection with optional strict anti-detect mode * One-click session switching with search, color avatars, and profile statistics * Rename, configure, or delete profiles directly from the popup * Configurable switching behavior and confirmation settings * Crash-safe switching with backup, wipe, restore, and recovery * Local-first architecture with data stored on your device * No account required, analytics, or tracking HOW IT WORKS 1. Click a profile in the popup to switch sessions. 2. Multisession backs up the current browser state, clears the active state, and restores the selected profile. 3. Tabs can automatically reload after switching so the restored session is immediately available. STRICT ANTI-DETECT (OPT-IN) Strict mode can modify User-Agent, Client Hints, and JavaScript fingerprint APIs for specialized browser testing and privacy workflows. This mode is optional and can be disabled when compatibility with CAPTCHA systems or websites requiring standard browser characteristics is important. PRIVACY-FIRST BY HTMLRUNNER Multisession is designed as a local-first browser tool. The extension does not operate servers that receive your browsing data and does not sell or sync your browser session data. Permissions such as cookies, storage, browsingData, tabs, scripting, declarativeNetRequest, and unlimitedStorage are used to provide the profile backup, isolation, and restoration functionality. The Privacy Policy and Terms are available from the extension's Settings.
