This page is the only official source.\n\n# Betterfox\n[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/).\n\n:new: Betterfox for [Firefox 153 ESR](https://github.com/yokoffing/Betterfox/tree/esr153#betterfox-153-esr) is now available\n\n## Made for everyday browsing\nMake Firefox more private and secure — without using third-party code.\n\nBetterfox 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).\n\n## Required reading\n0) Create a [backup profile](https://github.com/yokoffing/Betterfox/wiki/Backup).\n1) Download the user.js file [here](https://raw.githubusercontent.com/yokoffing/Betterfox/main/user.js) (Right click \u003e `Save Link As…`).\n2) 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.\n3) Open Firefox. In the URL bar, type `about:profiles` and press **Enter**.\n4) For the profile you want to use, click **Open Folder** in the **Root Directory** section.\n5) Move the `user.js` file into the folder.\n\n*After restarting Firefox:*\n1) 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).\n2) 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.\n\n## Simple goals\n1) **Minimalism:** get what isn't needed out of the way\n2) **Efficiency:** unleash Firefox's ability to be fast and performant\n3) **Privacy:** protect your data without causing site breakage\n\n## Simple configs\n\n`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.\n\n| List      | Description |\n|:---------:|-------------|\n| [user.js](https://github.com/yokoffing/Betterfox/blob/main/user.js) | All the essentials. None of the breakage. This is your `user.js`. |\n| [Securefox](https://github.com/yokoffing/Betterfox/blob/main/Securefox.js) | Protect user data without causing site breakage. |\n| [Peskyfox](https://github.com/yokoffing/Betterfox/blob/main/Peskyfox.js)  | Provide a clean, distraction-free browsing experience. |\n| [Smoothfox](https://github.com/yokoffing/Betterfox/blob/main/Smoothfox.js)\u003cbr\u003e(optional) | Get Edge-like smooth scrolling on your favorite browser — or choose something more your style. |\n\n## Recognition\n\n### Browser Integration\n\u003e [!IMPORTANT]\n\u003e 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.\n\n* [Zen](https://github.com/zen-browser/desktop?tab=readme-ov-file) | [files](https://github.com/zen-browser/desktop/tree/stable/prefs) (July 2024)\n* [FireDragon](https://github.com/dr460nf1r3/firedragon-browser/blob/master/README.md) | [files](https://github.com/dr460nf1r3/firedragon-browser/blob/55fc6e5029542cd90fabe23cb44c89568d74d006/firedragon.cfg#L822-L824) (Jan 2024?)\n* [Midori](https://github.com/goastian/midori-desktop/blob/ESR115/README.md) | [files](https://github.com/goastian/midori-desktop/blob/f3d8d96eb8e08f35a64e3c957bea4e839d7c7730/floorp/browser/components/userjsUtils.sys.mjs#L28-L33) (Dec 2023?)\n* [Mercury](https://github.com/Alex313031/Mercury/releases/tag/v.115.3.0) | [files](https://github.com/Alex313031/Mercury/commit/eb9600f9fb8f48c8f5b5c6f3264fbcdb5caff7f5) (Sep 2023)\n* [Waterfox](https://www.waterfox.net/docs/releases/G6.0/) | [files](https://github.com/WaterfoxCo/Waterfox/tree/current/waterfox/browser/app/profile) (Sep 2023)\n* [Floorp](https://github.com/Floorp-Projects/Floorp#-betterfox) \u003csup\u003e[1](https://github.com/Floorp-Projects/Floorp/issues/233#issuecomment-1543557167) [2](https://blog.ablaze.one/3135/2023-04-01/)\u003c/sup\u003e | [files](https://github.com/Floorp-Projects/Floorp/blob/ESR115/floorp/browser/components/preferences/userjs.inc.xhtml) (Apr 2023)\n* [Pulse](https://github.com/pulse-browser/browser#%EF%B8%8F-credits) | [files](https://github.com/pulse-browser/browser/tree/alpha/src/browser/app/profile) (Dec 2021)\n* [Ghostery Private Browser](https://github.com/ghostery/user-agent-desktop#community) \u003csup\u003e[1](https://web.archive.org/web/20210509171835/https://www.ghostery.com/ghostery-dawn-update-more/) [2](https://web.archive.org/web/20210921114333/https://www.ghostery.com/ghostery-dawn-product-update/)\u003c/sup\u003e | [files](https://github.com/ghostery/user-agent-desktop/tree/main/brands/ghostery/branding/pref) (Feb 2021)\n\n### YouTube\n* [A Better Firefox](https://youtu.be/JuHIwCFx34Q?si=1dx39t3HX5kzNVj-\u0026t=133) (Mar 2025)\n* [Ditch Chrome for One Of These BETTER BROWSERS!](https://youtu.be/ygkxFc8SZlc?si=m5NQe-b_oFXs5crb\u0026t=230) (Aug 2024)\n* [The ULTIMATE Browser Tier List](https://youtu.be/j5r6jFE8gic?t=560) (Mar 2023)\n* [I Hate Firefox.
