Multi-Login

Multi-Login — Per-Tab Session Isolation Tired of logging out and back in just to switch accounts? Multi-Login gives each tab its own isolated session, so you can be logged into Gmail, Twitter, GitHub, or any site with multiple accounts — all at the same time, in the same browser window. How It Works Each isolated tab gets its own virtual cookie jar and storage namespace. Your sessions are completely separated — no cross-contamination between tabs. Key Features - Isolate any tab with one click from the popup - Open a new pre-isolated tab instantly - Right-click any link to open it in an isolated tab - Isolated tabs show a green badge so you always know which ones are active - Links opened from an isolated tab automatically inherit the parent session - Sessions are ephemeral — close the tab and all traces are gone What Gets Isolated - Cookies (including HttpOnly) - localStorage - document.cookie - IndexedDB Privacy First No data leaves your browser. No accounts, no servers, no tracking. Sessions live entirely in memory and are destroyed when you close the tab. Use Cases - Manage multiple email accounts side by side - Test web apps with different user roles - Keep work and personal accounts separate - QA and development testing Perfect for developers, social media managers, QA testers, or anyone juggling multiple accounts.
