+
+Configure local network access security features.
+The `LocalNetworkAccess` policy controls Firefox's behavior when websites attempt to access local network resources (localhost and local network addresses).
+
+**Compatibility:** Firefox 150\
+**CCK2 Equivalent:** N/A\
+**Preferences Affected:** `network.lna.enabled`, `network.lna.block_trackers`, `network.lna.blocking`, `network.lna.skip-domains`
+
+## Values
+
+- `Enabled`: a Boolean that enables or disables the policy.
+  - When `true` (default), Firefox enforces local network access security checks.
+    This is the base flag without which none of the local network access checks below would be enforced.
+  - When `false`, all local network access checks are disabled and websites can freely access local network resources.
+- `BlockTrackers`: a Boolean that controls blocking third-party trackers. When `true`, third-party trackers are directly blocked from accessing localhost and local network resources.
+  This is an experimental feature that helps prevent tracking scripts from scanning your local network.
+- `EnablePrompting`: a Boolean to gate user permission prompts.
+  When `true`, access to local network resources will be explicitly gated via user permission prompts.
+  Users will be asked to grant permission before a website can access local resources.
+- `SkipDomains`: an array of domain names for which local network access checks should be skipped. This allows administrators to create exceptions for trusted domains.
+- `Locked`: if set to true, users cannot change the local network access settings.
+
+## Description
+
+When providing a list of exceptions for trusted domains, the `SkipDomains` array can contain both **source domains** (the website making the request) and **target domains** (the local resource being accessed).
+
+When a **source domain** is listed, that website is allowed to access local network resources without restrictions.
+For example, if `"trusted-app.example.com"` is listed, that website can freely make requests to any local network resources.
+
+When a **target domain** is listed, any website can access that specific local network resource without restrictions.
+For example, if `"printer.local"` is listed, all websites can access the printer device.
+
+Suffix wildcard patterns for are supported using the `*.` prefix to match all subdomains:
+
+- `"*.company.com"` - Skips checks for all subdomains of company.com (matches `app.company.com`, `portal.company.com`, etc.).
+- `"*.internal"` - Skips checks for all .internal domains (matches `device.internal`, `printer.internal`, etc.).
+- `"web-app.example.com"` - Skips checks for this specific domain only (no subdomain matching).
+- `"*.devices.local"` - Allows access to all local devices with `.devices.local` suffix (`printer.devices.local`, `scanner.devices.local`, etc.).
+- `"*.corp.internal"` - Allows access to all corporate internal domains.
