  description

  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, or 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 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
  
  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
  
  How it works
  • A trusted page or script sends a request through the local bridge
  • The extension remains the visible control point
  • The target page is handled as a dedicated managed tab
  • Allow-list rules and browser permissions keep actions explicit and bounded
  • If a restricted action is attempted, the extension blocks it and reports a security alert
  
  Privacy and security
  • Local-first operation
  • No backend
  • No proxy
  • No tracking
  • No cookie access
  • No arbitrary remote code execution
  • Only predefined extension actions are exposed
  • Requests are restricted by allow-list, browser permissions, domain lock, and site policies when present
  
  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

  • 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.
