🟥 Summary: Arkenfox v115.1+ makes approx 110 pref changes. Of those, a tiny few cover almost all usability issues

• Your mileage may vary
• You can always change your overrides at any time and "undo"/"redo" things
  • ⚠️ except deleted items (such as cookies, history and session restore)
• See that warning above? Now make sure to read the tiny few items below, because arkenfox deletes items by default

---

⭐ There is also an interactive version of the user.js at https://arkenfox.github.io/gui that you can:

• search, filter, collapse and expand to your heart's content
• use to lookup items, decide what to override, and troubleshoot

🟪 SECURITY

• 0403: We disable binary checks not in Safe Browsing local lists
  • ⚠️ If you do not understand the consequences, override this

🟪 KEEP LOGINS

• We delete all cookies and site data on close
  • There is no need to change any prefs - to keep some cookies and logins, just add site exceptions: either
    • Ctrl+I > Permissions > Cookies > Allow (when on the website in question)
    • ☰ Settings > Privacy & Security > Cookies & Site Data > Manage Exceptions
  • For cross-domain logins, add exceptions for both sites
    • e.g. https://www.youtube.com (site) + https://accounts.google.com (single sign on)
  • ⚠️ Be selective with what cookies you keep, as they also disable partitioning, see bugzilla 1767271

🟪 COMMON

• 0102: We disable session restore
  • If you rely on session restore, see our override recipe
• 0810: We disable search & form history
  • Form data can easily be stolen by third parties
    • see this 2017 article and bugzillas 1443083 + 1427543
    • see this 2011 article and bugzilla 381681
• 1223: We enforce strict pinning
  • Override if you have issues with antivirus
• 2811: We delete history (download, form and browsing histories) on close
  • And 2820 for manual sanitizing

🟪 OTHER

Other preferences may cause site breakage, but nothing that can't be fixed. You won't "lose" anything...- it's not the end of the world.

• Check our override recipes
• Check already answered issues
• While not 100% definitive, search for [SETUP in the user.js; e.g.
  • [SETUP-WEB] can cause some websites to break
  • [SETUP-CHROME] changes how Firefox itself behaves (i.e. NOT directly website related)
• You may also want to add items e.g.
  • 5000s optional
