   *  ⚠️ **This is a breaking change**:
   * Several `FxaAccountManager` methods have been made internal, and are no longer part of the public API of this module: `createSyncManager`, `getAccountStorage`.
 
+* **browser-state**
+  * ⚠️ **This is a breaking change**: `DownloadState` doesn't include the property `filePath` in its constructor anymore, now it is a computed property. As the previous behavior caused some situations where `fileName` was initially null and after assigned a value to produce `filePath` values like "/storage/emulated/0/Download/null" [for more info](https://sentry.prod.mozaws.net/operations/reference-browser/issues/6609701/).
