 You have 40 tabs open. You want to close all the duplicates, group the GitHub ones, save your session before a meeting, and open a few URLs into a specific group — all from a script. That is what browser-cli is for.

 ## Limitations
 
-- **Chrome internal pages** (`chrome://`, `brave://`, `about:`) cannot be scripted. DOM and extract commands only work on regular `http://` and `https://` pages.
+- **Browser internal pages** (`chrome://`, `brave://`, `edge://`, `about:`) cannot be scripted. DOM and extract commands only work on regular `http://` and `https://` pages.
 - **Multiple browser instances can be auto-distinguished, but generated aliases are temporary**. Unaliased browsers get UUID aliases from the native host, which avoids collisions but is less ergonomic than setting a stable alias with `browser-cli clients rename --browser <current-alias> <new-alias>`.
 - **Supported install targets are explicit, not “all Chromium browsers”**. The installer currently supports Chrome, Chromium, Brave, Edge, and Vivaldi. Other Chromium-based browsers may use different or shared native messaging manifest locations, so they need browser-specific verification before being added safely.
 - **Linux and macOS only** — Windows native messaging paths are not yet handled.
