 ## Limitations
 
 - **Chrome internal pages** (`chrome://`, `brave://`, `about:`) cannot be scripted. DOM and extract commands only work on regular `http://` and `https://` pages.
-- **Profile switching** via `windows open --profile` depends on browser support and does not replace launching a separate browser profile externally with `--profile-directory`.
 - **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 rename-profile --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.
