 ## 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!)

 // 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

 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!
