*    name: arkenfox user.js
*    date: 7 June 2024
* version: 126
*    urls: https://github.com/arkenfox/user.js [repo]
*        : https://arkenfox.github.io/gui/ [interactive]

* README:

  1. Consider using Tor Browser if it meets your needs or fits your threat model
       * https://2019.www.torproject.org/about/torusers.html
  2. Read the entire wiki
       * https://github.com/arkenfox/user.js/wiki
  3. If you skipped step 2, return to step 2
  4. Make changes in a user-overrides.js
       * There are often trade-offs and conflicts between security vs privacy vs anti-tracking
         and these need to be balanced against functionality & convenience & breakage
       * Some site breakage and unintended consequences will happen. Everyone's experience will differ
         e.g. some user data is erased on exit (section 2800), change this to suit your needs
       * While not 100% definitive, search for "[SETUP" tags
  5. Some tag info
       [SETUP-SECURITY] it's one item, read it
            [SETUP-WEB] can cause some websites to break
         [SETUP-CHROME] changes how Firefox itself behaves (i.e. not directly website related)
  6. Override Recipes: https://github.com/arkenfox/user.js/issues/1080
