Remote Tab Opener Manager

Secure, local-first tab control via a browser extension bridge + inter-extension Bridge API.

Remote Tab Opener Manager is a local-first browser extension that lets trusted, allow-listed pages control and supervise a dedicated browser tab through a visible extension bridge. It is designed for controlled browser workflows where an admin page, dashboard, local tool, or authorized script needs to open, reuse, navigate, refresh, focus, or close a separate target tab in a clear and user-controlled way. All actions run locally inside the browser. No backend, proxy, remote relay, tracking system, or user account is required. What the extension can do • Open a dedicated tab or reuse an existing one • Navigate, refresh, focus, or close the managed tab • Read basic target-tab metadata such as URL and title • Read allowed visible page content for supported workflows • Fill ordinary visible editable form fields when authorized • Display clearly marked RTO visual overlays • Keep the controlled tab visible and easier to supervise • Expose a secure inter-extension channel for trusted official RTO add-ons Safety boundaries • Password fields are not read or written • Hidden fields are not read or written • File fields are not controlled • Sensitive fields are protected • Normal website text, button labels, links, and page titles are not modified • RTO overlays are visually marked and cannot contain scripts, forms, clickable links, or action buttons • A managed tab remains limited to its authorized domain • Websites can publish an RTO Lock policy to restrict or disable RTO interactions • Unknown external extensions are refused by the RTO Trust Policy • Official add-ons do not receive automatic permission to bypass RTO security rules How it works • A trusted page, local tool, or authorized add-on sends a request through the local RTO bridge • The extension remains the visible control point • The target page is handled as a dedicated managed tab • Allow-list rules, browser permissions, domain lock, and site policies keep actions explicit and bounded • If a restricted action is attempted, the extension blocks it and reports a security alert • Official RTO add-ons can request actions, but RTO original remains the authority that authorizes and executes them Privacy and security • Local-first operation • No backend • No proxy • No tracking • No cookie access • No arbitrary remote code execution • No eval or dynamic remote script execution • Only predefined extension actions are exposed • Requests are restricted by allow-list, browser permissions, domain lock, RTO Lock, capability checks, and site policies when present • The secure add-on API checks the calling extension before accepting external requests Typical use cases • Admin dashboards that open and update a controlled working tab • Internal tools that coordinate a source page and a target page in the browser • Testing and supervision tools that need a dedicated managed tab • Developer-oriented workflows that require explicit, visible browser-side tab control • Official RTO add-ons that need to request browser actions without bypassing RTO security Remote Tab Opener Manager is intended for technical users and developer-oriented workflows that need transparent, local, browser-side tab supervision. Version 8.4.0 adds a secure inter-extension API for trusted official RTO add-ons. Normal RTO usage remains unchanged, and the add-on API does not bypass RTO Lock, allow-list checks, capability checks, or user-controlled browser execution.
