nothing of consequence... I promise a new clean issue for v102

• new in user.js v101
  • this is part of ETP Strict and will be used in FF102 by default, also see query stripping #1457

   // user_pref("privacy.query_stripping.enabled", true); // [FF101+] [ETP FF102+]

• removed in user.js v101
  • showing original arkenfox values below
  • these were all active (and now inactive under 0650 for prefsCleaner - RUN PREFSCLEANER )
  • noopener and window.name have been default true since FF79 and FF86 respectively
  • trimURLs is cosmetic fluff, see remove 0803: browser.urlbar.trimURLs ? #1473
  • cookie.thirdparty is slated for removal upstream and may cause issues with the lifetime cookie pref deprecation and site exceptions, and is also covered by sanitizing on close

user_pref("browser.urlbar.trimURLs", false);
user_pref("dom.targetBlankNoOpener.enabled", true);
user_pref("network.cookie.thirdparty.sessionOnly", true);
user_pref("network.cookie.thirdparty.nonsecureSessionOnly", true);
user_pref("privacy.window.name.update.enabled", true);

OTHER NEWS

• revamped new shiny improved simpler faster stronger lighter cleaner magnificently stupendously awesome wiki
  • still a couple of things to do, but mostly done
  • thanks everyone for their feedback
  • see new wiki #1354 if you want
• fission
  • since we opt of out of rollouts, we had to wait for the pref flips in stable
• @fxbrit (aka 🐟 ) is an admin for this repo
  • congrats 🐟
  • 🐟 is a maintainer for Librewolf (LW) mac
  • 🐟 is more than that though. I have been working behinds the scenes with 🐟 for about a year: initially for selfish reasons: to align LW more with AF so as to not give AF a bad rep (there is/was a perception that LW was essentially AF)
  • In that time, LW and AF are now almost identical (for things that matter), and in fact, a few changes have resulted because we have worked together to clean things up: such as WebRTC
  • 🎉 party at fxbrit's house

CHANGELOG: [all changes]

• links to bugzilla tickets and default pref changes in Firefox are in our ToDo: diffs FF96-FF97 issue
• v97 PR is at v97 #1346 ¹
• for all the rest see the full list of pref changes below

¹ see #1299 - starting with v97, all changes to the live master happen once per release: all changes are done in a separate branch/PR and only merged when finished

⭐ your friendly reminder to ALWAYS run prefsCleaner

CHANGES

• new in user.js v97

user_pref("browser.places.speculativeConnect.enabled", false); // [FF98+]

• made inactive in user.js v97
  • 0403 browser.safebrowsing.downloads.remote.enabled is already false
  • this makes it easier for users to override since the pref needs to be "looked up"

   // user_pref("browser.safebrowsing.downloads.remote.url", ""); // Defense-in-depth
