# Betterfox
[about:config](https://support.mozilla.org/en-US/kb/about-config-editor-firefox) tweaks to enhance [Mozilla Firefox](https://www.mozilla.org/en-US/firefox/new/).
## Made for everyday browsing
Make Firefox more private and secure — without using third-party code.
Betterfox is an opinionated preference list inspired by the [law of diminishing returns](https://miro.medium.com/v2/resize:fit:1206/1*lcOcxriV_II_lZuXQYLoXg.jpeg) and the [minimum effective dose](https://medium.com/the-mission/less-is-more-the-minimum-effective-dose-e6d56625931e).
## Required reading
0) Create a [backup profile](https://github.com/yokoffing/Betterfox/wiki/Backup).
1) Download the user.js file [here](https://raw.githubusercontent.com/yokoffing/Betterfox/main/user.js) (Right click > `Save Link As…`).
2) Review both [Common Overrides](https://github.com/yokoffing/Betterfox/wiki/Common-Overrides) and [Optional Hardening](https://github.com/yokoffing/Betterfox/wiki/Optional-Hardening) to make any necessary changes.
3) Open Firefox. In the URL bar, type `about:profiles` and press **Enter**.
4) For the profile you want to use, click **Open Folder** in the **Root Directory** section.
5) Move the `user.js` file into the folder.
*After restarting Firefox:*
1) Get an **ad blocker** like [uBlock Origin](https://addons.mozilla.org/blog/ublock-origin-everything-you-need-to-know-about-the-ad-blocker/) with our [recommended filters](https://github.com/yokoffing/filterlists#guidelines).
2) Enable **DNS-level protection** with your chosen [provider](https://github.com/yokoffing/Betterfox/wiki/Optional-Hardening#secure-dns) to further protect against security threats, ads, and trackers.
## Simple goals
1) **Minimalism:** get what isn't needed out of the way
2) **Efficiency:** unleash Firefox's ability to be fast and performant
3) **Privacy:** protect your data without causing site breakage
## Simple configs
`Securefox`, `Peskyfox`, and `Smoothfox` are guides to settings within Firefox. The `user.js` — a configuration file that controls Firefox settings — is curated from these guides.
| List | Description |
|:---------:|-------------|
| [user.js](https://github.com/yokoffing/Betterfox/blob/main/user.js) | All the essentials. None of the breakage. This is your `user.js`. |
| [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) (optional) | Get Edge-like smooth scrolling on your favorite browser — or choose something more your style. |

### Browser Integration
> [!IMPORTANT]
> While the browsers listed below incorporate Betterfox to some extent, they often modify it in ways that reduce its effectiveness. For optimal results, apply the `user.js` file even when using Firefox forks.
