-
-The `user.js` — a configuration file that controls Firefox settings — is curated from these guides.

-| List      | Description |
-|:---------:|-------------|
-| [Fastfox](https://github.com/yokoffing/Betterfox/blob/main/Fastfox.js)   | Increase Firefox's browsing speed. Give Chrome a run for its money!|
-| [Securefox](https://github.com/yokoffing/Betterfox/blob/main/Securefox.js) | Protect user data without causing site breakage. |
-| [Peskyfox](https://github.com/yokoffing/Betterfox/blob/main/Peskyfox.js)  | Provide a clean, distraction-free browsing experience. |
-| [Smoothfox](https://github.com/yokoffing/Betterfox/blob/main/Smoothfox.js) | Get Edge-like smooth scrolling on your favorite browser — or choose something more your style. |
-| [user.js](https://github.com/yokoffing/Betterfox/blob/main/user.js) | All the essentials. None of the breakage. This is your `user.js`. |
