 ## BEFORE YOU BEGIN
 I have attempted the following troubleshooting suggestions:
-- [ ] [Cleared website data](https://www.hostinger.com/tutorials/wp-content/uploads/sites/2/2018/05/clear-browser-cache-firefox.png), restarted Firefox, and my issue persists.
-- [ ] No issues when using the website or extension in another web browser.
-- [ ] The issue persists when using Firefox in [Safe Mode](https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode#w_how-to-start-firefox-in-safe-mode).
-- [ ] Disabled DNS-level content blocking (AdGuard, NextDNS, PiHole), [cleared my DNS cache](https://www.pcmag.com/how-to/how-to-flush-your-dns-cache), and used my ISP's DNS resolver (if applicable).
+- [ ] The issue persists when using Firefox in [Troubleshoot Mode](https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode).
+- [ ] Disabled DNS-level content blocking (AdGuard Home, NextDNS, Control D, RethinkDNS, PiHole, etc), [cleared my DNS cache](https://www.pcmag.com/how-to/how-to-flush-your-dns-cache), and used my ISP's DNS resolver (if applicable).
+- [ ] [Cleared website data](https://support.mozilla.org/en-US/kb/clear-cookies-and-site-data-firefox), restarted Firefox, and my issue persists.
+- [ ] I have created a [new profile](https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles). The issue persists when using the current [user.js](https://github.com/yokoffing/Betterfox/blob/master/user.js) file on GitHub. (Must be in a new profile and a new user.js!)

+// loads pages faster because the network can be quicker than accessing the cache
+// on a hard drive. When RCWN is enabled, the request might be served from

+// intention is to increase cache usage and reduce network usage.

 # 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/). 
 
+31% [faster](https://medium.com/@mihirgrand/comparing-popular-firefox-forks-6fa83fdfdaad#:~:text=31%25%20more%20than%20vanilla%20Firefox) than regular Firefox :rocket:
 
-## 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 😓
+Now with support for ESR [128](https://github.com/yokoffing/Betterfox/tree/esr128) :new: 
 
+## 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 [Common Overrides](https://github.com/yokoffing/Betterfox/wiki/Common-Overrides) and make any necessary changes.
+   * See also [Optional Hardening](https://github.com/yokoffing/Betterfox/wiki/Optional-Hardening) for other recommendations.
+3) Open Firefox. In the URL bar, type `about:profiles` and press **Enter**.
+4) For the profile you want to use (or use default), 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 [NextDNS](https://nextdns.io/?from=xujj63g5). <sup><i>Use the link and support this page!</i></sup>
+    * Check out our configuration [guide](https://github.com/yokoffing/NextDNS-Config) for the best experience.
+    * See how to [quickly enable](https://support.mozilla.org/en-US/kb/dns-over-https) **secure DNS** in Firefox.
+
+## 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://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).
 
 ## 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
 
+`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.
+
 | List      | Description |
 |:---------:|-------------|
-| [Securefox](https://github.com/yokoffing/Betterfox/blob/master/Securefox.js) | Remove Telemetry, Mozilla experiments, Google Safe Browsing, and search engine suggestions in URL bar. Auto-upgrade mixed content to HTTPS. Various privacy enhancements. |
-| [Peskyfox](https://github.com/yokoffing/Betterfox/blob/master/Peskyfox.js)  | Unclutter the new tab page. Remove Pocket and form autofill. Prevent Firefox from serving annoying webpage notifications. |
-| [Fastfox](https://github.com/yokoffing/Betterfox/blob/master/Fastfox.js)   | Immensely increase Firefox's browsing speed. Give Chrome a run for its money!|
-| [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 essentails. None of the breakage. Users may download this list as their own user.js. |
+| [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`. |
 
-: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.
+## Recognition
 
-## 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).
+### 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.
 
-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.

-## 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). If you have no other form of protection, then please re-enable GSB.
-* 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 re-enable Firefox's password management.
-* **Firefox Sync** and **Firefox View** are disabled.
-* **Site notifications** are disabled.
-* **Location requests** are rejected.
-* **Embedded tweets, instagram, and reddit posts** 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).
-   * Advanced users: We suggest that you [selectively allow](https://github.com/gorhill/uBlock/wiki/Dynamic-filtering:-quick-guide) these requests in [uBlock Origin](https://addons.mozilla.org/blog/ublock-origin-everything-you-need-to-know-about-the-ad-blocker/) with [medium mode](https://github.com/gorhill/uBlock/wiki/Blocking-mode:-medium-mode) enabled + add the [Privacy Essentials](https://github.com/yokoffing/filterlists/blob/main/privacy_essentials.txt) filter to your [custom lists](https://github.com/gorhill/uBlock/wiki/Dashboard:-Filter-lists#3rd-party-filter-lists).
-* 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.
-* If your threat level calls for _anonymity_ and not just reasonable _privacy_,<sup>[1](https://thenewoil.org/secprivanon.html)</sup> please use the [TOR browser](https://www.torproject.org).

+install(-betterfox).py
+
+Usage:
+    python install.py
+    
+
+When called without arguments, it will:
+- Backup your current firefox profile
+- Automatically download user.js from the latest Betterfox release compatible with your Firefox version into the profile
+- Apply user-overrides in the same directory 
+
+However, you can check out install.py/betterfox-install.exe --help to customise most behaviours!
+
+Limitations:
+- When using a different repositoy as a source, that repository needs to use the same releases workflow
+- Over time, the get_releases might not list older releases due to limited page size. This can be expanded down the road, though
+
+Building into an exe (on Windows):
+- pipx install pyinstaller  (note: you can try without pipx, but this didn't work for me)
+- Run:
+  - CMD:  `pyinstaller --onefile --name install-betterfox install.py && move %cd%\\dist\\install-betterfox.exe %cd% && del install-betterfox.spec && rmdir /S /Q build && rmdir dist`
+  - BASH: `pyinstaller --onefile --name install-betterfox install.py && && mv dist/install-betterfox.exe . && rm install-betterfox.spec && rm -rf ./build/ && rmdir dist`
+  (Sorry, didn't want to add a .gitignore solely for the install script)
+- Done!
+
+If there's any problems with the script, feel free to mention @Denperidge on GitHub!
