+## BEFORE YOU BEGIN
+I have attempted the following troubleshooting suggestions:
+- [ ] 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!)

+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 your chosen [provider](https://github.com/yokoffing/Betterfox/wiki/Optional-Hardening#secure-dns) to further protect against security threats, ads, and trackers.
+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.

-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!

-#### A user.js for Waterfox
-Just FYI: There are some long-term issues with Waterfox where the browser doesn't load certain internal settings or resets prefs after restart. For examples, see https://github.com/BrowserWorks/waterfox/issues/3196 and https://github.com/BrowserWorks/waterfox/issues/3947.

-> [!IMPORTANT]
-> Fork-specific files are side projects and will not update every release. When in doubt, use the standard Firefox user.js.
