+# KeePassGO Browser Extension
+
+Shared extension assets for Firefox and Chromium-based browsers live here.
+
+- `manifest.firefox.json` uses the fixed Firefox extension id `browser@keepassgo.invalid`
+- `manifest.chromium.json` is the Chromium/Chrome manifest template
+- `background.js` talks to the native messaging host `org.keepassgo.browser`
+- `content.js` fills username and password fields on the current page
+- `options.html` stores the local gRPC address and API token in browser extension storage
+
+The extension sends the API token to the native host on each request. The bridge does not store the token on disk.

+# Browser Extension
+
+KeePassGO browser integration uses:
+
+- the existing local gRPC API in KeePassGO
+- API tokens for authorization
+- a tiny native messaging host for browser-to-gRPC transport adaptation
+
+The browser extension does **not** talk to vault files directly.
+
+## Security Model
+
+- KeePassGO remains the source of truth for authentication, authorization, approvals, and audit events.
+- The browser extension stores the gRPC address and API token in browser extension storage.
+- The native messaging host receives the token on each request from the extension.
+- The native messaging host uses the token only to attach `authorization: Bearer ...` metadata to the local gRPC request.
+- The native messaging host does not persist the token to disk.
+
+The native messaging host is therefore part of the trusted client for that browser profile. Scope the API token accordingly.
+
+## RPCs Used
+
+The browser integration uses:
+
+- `GetSessionStatus`
+- `FindBrowserLogins`
+- `GetBrowserCredential`
+
+The browser feature intentionally stays on the same secure gRPC surface used by other trusted automation.
+
+## Native Host
+
+Build the bridge:
+
+```bash
+go build ./cmd/keepassgo-browser-bridge
+```
+
+Install a Firefox native messaging manifest:
+
+```bash
+./keepassgo-browser-bridge install-native-host --browser firefox --binary /absolute/path/to/keepassgo-browser-bridge
+```
+
+Install a Chromium native messaging manifest:
+
+```bash
+./keepassgo-browser-bridge install-native-host --browser chromium --binary /absolute/path/to/keepassgo-browser-bridge --extension-id <your-extension-id>
+```
+
+Chrome and Chromium require the actual extension id in the native host manifest.
+
+## Extension Setup
+
+Firefox:
+
+1. Load `browser/extension/manifest.firefox.json` as a temporary add-on or package it as an extension.
+2. Open the extension settings page.
+3. Set the KeePassGO gRPC address, usually `127.0.0.1:47777`.
+4. Paste an API token scoped for browser login lookup and credential copy.
+
+Chromium / Chrome:
+
+1. Load `browser/extension/` with `manifest.chromium.json`.
+2. Note the extension id the browser assigns.
+3. Install the native host manifest with that extension id.
+4. Configure the gRPC address and API token in the extension settings page.
+
+## Required Token Scope
+
+At minimum, the browser token should have policy rules allowing:
+
+- `list_entries` for the groups you want the browser to search
+- `copy_username` for entries the browser may fill
+- `copy_password` for entries the browser may fill
+- `copy_url` for entries the browser may confirm against page URL
