### :small_orange_diamond: Check your `"parrot"` and console
When you modify your user.js, such as adding any overrides, sometimes syntax errors happen. Open about:config and check your `"parrot"`. Arkenfox uses `_user.js.parrot` throughout the user.js. You can use any pref name you like, as long as it's different (to avoid confusion). Note: [not all](https://blog.mozilla.org/nnethercote/2018/03/09/a-new-preferences-parser-for-firefox/) syntax errors cause the user.js parsing to be aborted. After Firefox opens, open the Browser Console (`Ctrl+Shift+J`) and check for any pref-parsing related warnings/errors.
