 # Betterfox
-about:config tweaks to enhance [Mozilla Firefox](https://www.mozilla.org/en-US/firefox/new/ "Firefox Homepage"). Files are updated as needed for your [user.js](http://kb.mozillazine.org/User.js_file).
+[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/). 

+:new: Now with [ESR support](https://github.com/yokoffing/Betterfox/tree/esr115#betterfox-esr).

-## Who is this setup for?
-**If you want a secure, blazing fast browsing experience, and don't want to deal with breakage, this setup is for you.** The objective is to make the defaults sufficient enough for the average privacy-minded user, but remain trouble-free enough that my grandmother could use it. <strike>(That puts a whole new twist on being a foxy grandma!)</strike> Edit: Sorry for the dad joke 😓
+## Made for everyday browsing
+**A secure, blazing fast browsing experience. Without breakage.**

+Betterfox is an opinionated preference list inspired by the [law of diminishing returns](https://pmctraining.com/site/wp-content/uploads/2018/04/Law-of-Diminishing-Returns-CHART.png) and the [minimum effective dose](https://medium.com/the-mission/less-is-more-the-minimum-effective-dose-e6d56625931e).

 ## 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) **Security:** sensible privacy and security without causing site breakage
-
+3) **Privacy:** protect your data without causing site breakage

 ## Simple configs

 | List      | Description |
 |:---------:|-------------|

-| [Smoothfox](https://github.com/yokoffing/Betterfox/blob/master/Smoothfox.js) | Get Microsoft Edge-like smooth scrolling on your favorite browser. |
-| [user.js](https://github.com/yokoffing/Betterfox/blob/master/user.js) | All the essentials. None of the breakage. Users may download this list as their own user.js. |
+| [Fastfox](https://github.com/yokoffing/Betterfox/blob/main/Fastfox.js)   | Immensely increase Firefox's browsing speed. Give Chrome a run for its money!|

Enhanced [state](https://developer.mozilla.org/en-US/docs/Web/Privacy/State_Partitioning) and [network](https://blog.mozilla.org/security/2021/01/26/supercookie-protections/) partitioning. [Telemetry](https://github.com/yokoffing/Betterfox/blob/e66a549985f6b0db4b14226904b8c09eaaea998f/Securefox.js#L1262-L1265) disabled. |
+| [Peskyfox](https://github.com/yokoffing/Betterfox/blob/main/Peskyfox.js)  | Unclutter the new tab page. Remove [Pocket](https://support.mozilla.org/en-US/kb/what-pocket).

+| [user.js](https://github.com/yokoffing/Betterfox/blob/main/user.js) | All the essentials. None of the breakage. This is your `user.js`. |

-:bulb: `Securefox`, `Peskyfox`, `Fastfox`, and `Smoothfox` are guides to relevant prefs in Firefox. The `user.js` is curated from the prefs located in these documents, so just because a pref is in one of the guides doesn't mean it is included in the final document, the `user.js`. Please use the descriptions and references as a guide for the prefs in Firefox, and open a [feature request](https://github.com/yokoffing/Betterfox/issues/new/choose) if you think one can be improved upon.
+`Fastfox`, `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.
+
+## Getting started
+*If you don't have it already: [Get Firefox](https://www.mozilla.org/en-US/firefox/all/#product-desktop-release)*
+
+1) Create a [backup profile](https://github.com/yokoffing/Betterfox/wiki/Backup).
+2) Download the user.js file [here](https://raw.githubusercontent.com/yokoffing/Betterfox/main/user.js) (Right click > `Save Link As…`).
+3) Review [Common Overrides](https://github.com/yokoffing/Betterfox/wiki/Common-Overrides) and make any necessary changes.
+4) Open Firefox. In the URL bar, type `about:profiles` and press `Enter`.
+5) For the profile you want to use (or use default), click `Open Folder` in the **Root Directory** section.
+6) 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). For a simple solution, use [Ghostery](https://addons.mozilla.org/en-US/firefox/addon/ghostery/).
+2) Enable **DNS-level protection** with [NextDNS](https://nextdns.io/?from=xujj63g5), and check out our configuration [guide](https://github.com/yokoffing/NextDNS-Config).
+    * See how to [quickly enable](https://support.mozilla.org/en-US/kb/dns-over-https) **secure DNS** in Firefox.

 ## about:Privacy
-The guiding principle is: "If it breaks it, it doesn't make it!" So things like WebGL and DRM are still enabled, and you won't find a setting like `privacy.resistFingerprinting` mentioned here ([why?](https://old.reddit.com/r/firefox/comments/wuqpgi/are_there_any_aboutconfig_tweaks_to_get_smooth/ile3whx/?context=3)). Betterfox is designed to set-and-forget, not to troubleshoot and tinker. You can compare different user.js files [here](https://jm42.github.io/compare-user.js).
+Betterfox is a great balance of privacy and convenience.

-Betterfox was created with a [less is more](https://medium.com/the-mission/less-is-more-the-minimum-effective-dose-e6d56625931e) mentality (i.e., keeping in mind [the law of diminishing returns](https://pmctraining.com/site/wp-content/uploads/2018/04/Law-of-Diminishing-Returns-CHART.png)). Most repos I've encountered have niche privacy and security concerns with little regard for speed, annoyances, or mainstream use. The average user doesn't need all `prefs` altered to get the results they want.
+See [Optional Hardening](https://github.com/yokoffing/Betterfox/wiki/Optional-Hardening) for other suggestions.

-## Assumptions
-If you use any of the features below, please view the [common overrides](https://github.com/yokoffing/Betterfox/issues/87) sticky to restore functionality.
-* **Google Safe Browsing** (GSB) is disabled. We recommend use DNS-level protection like [NextDNS](https://nextdns.io/?from=xujj63g5), so check out our configuration guide [here](https://github.com/yokoffing/NextDNS-Config). :warning: If you have no other form of protection, then please enable GSB!
-* Firefox **Accessibility Service** is disabled to improve resource utilization and security. This will impact external application autofill capability (the ability to use a keyboard shortcut to fill in forms including logins) and screen readers. If you use assistive software, override this.
-* The native **password manager** is also disabled. If you don't use something like [KeePass](https://addons.mozilla.org/en-US/firefox/addon/keepassxc-browser/), [Bitwarden](https://addons.mozilla.org/en-US/firefox/addon/bitwarden-password-manager/), or [1Password](https://addons.mozilla.org/en-US/firefox/addon/1password-x-password-manager), then enable Firefox's password management.
-* **Embedded tweets, instagram, reddit posts, and tiktoks** load on webpages, even though these requests are usually blocked when using Firefox's [Strict Enhanced Tracking Protection](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#w_strict-enhanced-tracking-protection).
-* **Firefox Sync** and **Firefox View** are disabled.
-* **Site notifications** are disabled.
-* **Location requests** are rejected.
-* Since Firefox implemented [state](https://github.com/yokoffing/Betterfox/blob/537eb902106f5cacebfd7a77555193ba4573dc6e/SecureFox.js#L73-L88) and [network](https://github.com/yokoffing/Betterfox/blob/537eb902106f5cacebfd7a77555193ba4573dc6e/SecureFox.js#L93-L100) **partitioning**, it is recommended but no longer necessary to clear browsing data after every session.
-* [Fingerprinting](https://smartframe.io/blog/browser-fingerprinting-everything-you-need-to-know/) is a high [threat model](https://thenewoil.org/threatmodel.html) issue and is only addressed reasonably by TOR.<sup>[1](https://youtu.be/5NrbdO4yWek?t=4334)</sup> If your threat level calls for _anonymity_ and not just reasonable _privacy_, then please use the [TOR browser](https://www.torproject.org).
