  - Fennec [68 or lower]: some prefs may not apply, or may cause issues, or may be missing
- - Fenix [69+]: Don't do it! The differences in prefs is massive, and FYI: `about:config` is not available on release builds
+ - Fenix / GeckoView [69+]: **DON'T DO IT**❗ FYI: `about:config` is not available on release builds

+    >  - Android is a much different beast than the desktop platforms. *Settings commonly used on desktop may not work the same way that they do on Android!* Those of you who try to copy-paste settings from existing desktop guides will be in for a surprise. And no, it’s not just obscure settings that might work differently! Some of your more “common” settings may work completely differently, not at all, *or may actually break your Fenix installation!*
+    >  - Fenix uses GeckoView. For GeckoView (the embedding layer) to integrate with Gecko (the rendering engine), some settings must remain set in a specific way, or else Fenix would become completely detached from Gecko. Without losing your profile by reinstalling, *the only way you can undo that is if your phone is rooted!*
