 ## 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!)

 // Firefox concurrently sends requests for cached resources to both the

 // 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
 // the server even if you have valid entry in the cache. Set to false if your
 // intention is to increase cache usage and reduce network usage.

 [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/).
 ## Made for everyday browsing
 Make Firefox more private and secure — without using third-party code.
 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 configs
 `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 |
 |:---------:|-------------|
 | [user.js](https://github.com/yokoffing/Betterfox/blob/main/user.js) | All the essentials. None of the breakage. This is your `user.js`. |
 | [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)<br>(optional) | Get Edge-like smooth scrolling on your favorite browser — or choose something more your style. |

 ### 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.

 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!

 ### Betterfox Aqua
 #### 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.
 >
 > This is also a reminder that Waterfox is based on the [Firefox ESR](https://support.mozilla.org/kb/firefox-esr-release-cycle) release cycle.
