/* override recipe: enable session restore ***/
user_pref("browser.startup.page", 3); // 0102
  // user_pref("browser.privatebrowsing.autostart", false); // 0110 required if you had it set as true
  // user_pref("browser.sessionstore.privacy_level", 0); // 1003 optional to restore cookies/formdata

⭐ This is now inactive in arkenfox v128 see #1804

🔻 I don't want RFP

are you sure?

RFP also includes timing mitigations

• consider using problematic sites like gaming in a secondary browser
• if you're still concerned about fingerprinting, use CanvasBlocker with canvas and maybe webgl (the rest is not needed)

/* override recipe: RFP is not for me ***/
user_pref("privacy.resistFingerprinting", false); // 4501
user_pref("privacy.resistFingerprinting.letterboxing", false); // 4504 [pointless if not using RFP]
user_pref("webgl.disabled", false); // 4520 [mostly pointless if not using RFP]

⭐ This is now inactive in arkenfox v115.1+ see #1707

🔻 enable DRM: Netflix, HBO, Disney+, Amazon Prime, Showtime, Hulu, DirectTV, Starz, Sling ...

• TEST: https://bitmovin.com/demos/drm [i.e. get rid of the enable DRM prompt]

/* override recipe: enable DRM and let me watch videos ***/
   // user_pref("media.gmp-widevinecdm.enabled", true); // 2021 default-inactive in user.js and removed in user.js 115.1
user_pref("media.eme.enabled", true); // 2022

---

⭐ This is now the default in arkenfox v96, see #1281

Arkenfox will not support configurations in ETP custom mode moving forward

🔻 use ETP Strict mode

• Strict mode includes Total Cookie Protection and Smart Block and a stricter list, and works better with Enhanced Cookie Clearing

/* override recipe: FF87+ use ETP Strict mode ***/
user_pref("browser.contentblocking.category", "strict"); // 2701
user_pref("privacy.firstparty.isolate", false); // 6008: default false arkenfox v96
user_pref("network.cookie.cookieBehavior", 5); // 7016 inactive v96 [set at runtime by category=strict]

---

⭐ This is now the default in arkenfox v95, see #1286

🔻 RFP users: allow bigger default sizes for new windows (new win includes startup)

By all means, if you want bigger, go for it. This is not Tor Browser and the web needs to be usable for you

/* override-recipe: desktop: alter new window max sizes **/
   // user_pref("privacy.window.maxInnerWidth", 1600); // 4502 [default 1600 in user.js v95]
   // user_pref("privacy.window.maxInnerHeight", 900);  // 4502 [default 900 in user.js v95]

⭐ This is now the default in arkenfox v95, see #1282

🔻 enable web conferencing (thanks @rusty-snake, @mlario, @crssi )

/* override recipe: enable web conferencing: Google Meet | JitsiMeet | BigBlueButton | Zoom | Discord ***/

// OPTIONAL
   // some sites, e.g. Zoom, need a canvas site exception if using RFP [Right Click>View Page Info>Permissions]
   // user_pref("media.autoplay.blocking_policy", 0); // 2031 optional [otherwise add site exceptions]
   // user_pref("webgl.disabled", false); // 4520 optional [required for Zoom]

// RESET these - all now inactive or removed from user.js
   // ^ except media.peerconnection.ice.no_host can be used to harden if it works for you
   // user_pref("media.peerconnection.enabled", true); // 2001 default-inactive in user.js 95
   // user_pref("media.peerconnection.ice.no_host", false); // 2004 default-inactive in user.js 95
   // user_pref("javascript.options.wasm", true); // 5506 default-inactive in user.js v91
   // user_pref("dom.webaudio.enabled", true); // 8001 default-inactive in user.js v90
   // user_pref("media.getusermedia.screensharing.enabled", true); // removed from user.js v91
