 // When Firefox is loading a page, it periodically reformats

 # 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).

 ## Made for everyday browsing
-**A secure, blazing fast browsing experience. Without breakage.** 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 😓
+**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

+
+## 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
-Most repos have niche privacy and security concerns with little regard for speed, annoyances, or mainstream use. Betterfox was 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). For instance, features like WebGL and DRM are still enabled, and you won't find a setting like `privacy.resistFingerprinting` mentioned here<sup>^[*why?*](https://old.reddit.com/r/firefox/comments/wuqpgi/are_there_any_aboutconfig_tweaks_to_get_smooth/ile3whx/?context=3)</sup>. And while Betterfox is designed to set-and-forget, it contains plenty of options for those who like to tinker.
+Betterfox is a great balance of privacy and convenience.

-If your context calls for _anonymity_ and not just reasonable _privacy_, then please use [Tor Browser](https://www.torproject.org).<sup>[1](https://youtu.be/5NrbdO4yWek?t=4334)</sup> [Fingerprinting](https://smartframe.io/blog/browser-fingerprinting-everything-you-need-to-know/) is a high [threat model](https://thenewoil.org/threatmodel.html) issue that is [only addressed reasonably by Tor](https://github.com/arkenfox/user.js/wiki/3.3-Overrides-%5BTo-RFP-or-Not%5D).
-
-## Assumptions
-Apply preferences from the [common overrides](https://github.com/yokoffing/Betterfox/issues/87) sticky if you want to revert the following behavior:
-* Firefox **Accessibility Service** is disabled to improve resource utilization and security. Override this if you use assistive software.
-* **Embedded tweets, instagram, reddit posts, and tiktoks** load on webpages, even though these requests are usually blocked when using [Strict Enhanced Tracking Protection](https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop#w_strict-enhanced-tracking-protection).
-* The native **password manager** is disabled. We recommend using [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).
-* **Firefox Sync** and **Firefox View** are disabled.
-* **Location requests** are rejected and **site notifications** are disabled.
-
-### Suggestions
-1) Enable **sanitize on close** ([clear browsing data on shutdown](https://github.com/yokoffing/Betterfox/blob/99f2e860633f307781ddb73d792358ad1bec6af5/Securefox.js#L409-L434)).
-   * You can **allow exceptions** if you want to stay logged in to some sites in *Settings → Privacy & Security → Cookies and Site Data → Manage Exceptions*.
-   * Check *Delete cookies and site data when Firefox is closed*.
-2) Use [uBlock Origin](https://addons.mozilla.org/blog/ublock-origin-everything-you-need-to-know-about-the-ad-blocker/) or [Ghostery](https://addons.mozilla.org/en-US/firefox/addon/ghostery/) to block ads and trackers.
-3) Add DNS-level protection like [NextDNS](https://nextdns.io/?from=xujj63g5). Check out our configuration guide [here](https://github.com/yokoffing/NextDNS-Config).
+See [Optional Hardening](https://github.com/yokoffing/Betterfox/wiki/Optional-Hardening) for other suggestions.
