+Defines policies scoped to specific sites.
+
+**Compatibility:** Firefox 150, Firefox ESR 153\
+**Preferences Affected:** N/A
+
+The policy is made up of a list of rules that are evaluated in order. Each can contain:
+
+- `Match` which is a list of sites. An empty list or missing property means to match all sites.
+- `Exceptions` is also a list of sites which when matched bypasses this set of rules.
+- `Policies` is an object defining the policies.
+
+Currently the only supported policies are:
+
+- `DisableJit` which when true disables the JIT engine for the site.
+
+It is important to note that a site here refers to a registerable domain so `*.example.com` is a valid site but `*.com` is not. `*` can also be used to refer to all sites.
+
+For example this setting would disable the JIT for only `*.example.com`:
+
+```json
+[
+  {
+    "Match": ["*.example.com"],
+    "Policies": {
+      "DisableJit": true
+    }
+  }
+]
+```
+
+While this setting would disable the JIT on every site except `*.example.org`:
+
+```json
+[
+  {
+    "Exceptions": ["*.example.org"],
+    "Policies": {
+      "DisableJit": true
+    }
+  }
+]
+```
