 You can't call `eval()` on privileged browser windows such as "about:addons".
 
+In Firefox 153 and later, calling `eval()` on a `file://` URL requires the extension to be granted file scheme access by the user. Without this permission, the promise rejects with an error. Use {{WebExtAPIRef("extension.isAllowedFileSchemeAccess()")}} to check whether the user has granted the extension this permission.
+
 You can optionally provide an `options` parameter, which includes options to evaluate the script in a different frame or in the context of attached content scripts. Note that Firefox does not yet support the `options` parameter.
 
 The `eval()` function returns a [`Promise`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) that resolves to the evaluated result of the script or to an error.

 ## Changes for add-on developers
 
+- Extensions now require explicit user permission to access `file://` URLs. Previously, access to local files was covered by the "Access your data for all websites" host permission. This change introduces a separate "Access local files on your computer" option in the extension's permissions settings (desktop only), and file access is turned off by default for all extensions, including existing ones. The {{WebExtAPIRef("extension.isAllowedFileSchemeAccess()")}} method now correctly returns `true` if the user has granted file scheme access; previously, Firefox always returned `false`. Additionally, calling {{WebExtAPIRef("devtools.inspectedWindow.eval()")}} on `file://` URLs now requires this permission. ([Firefox bug 2034168](https://bugzil.la/2034168))
