librewolf

Portable LibreWolf theming — Betterfox 152 + qutefox-minimal (compact one-liners + autohide toolbars) — restore your LibreWolf exactly every time or push updates.

• user.js → Betterfox + toolkit.legacyUserProfileCustomizations.stylesheets=true + prefs
• chrome/userChrome.css → qutefox-minimal: JetBrains Mono tabs/urlbar, 26px tabs, square buttons, autohide bookmarks + toolbars (500ms)
• chrome/userContent.css → dark about:home / about:newtab / about:blank / about:privatebrowsing (#1a1b26)
• Extensions kept separate (install via LibreWolf, listed below)

Profile source

Captured from AppData\Roaming\LibreWolf\Profiles\main (profiles.ini: main)

# profiles.ini.example
[Profile0]
Name=main
Path=Profiles/main

Install / Restore (Windows)

# 1) Clone
git clone git@github.com:0124212/librewolf.git $env:USERPROFILE\librewolf
# 2) Apply (copies chrome + user.js into current LibreWolf profile)
powershell -ExecutionPolicy Bypass -File "$env:USERPROFILE\librewolf\install.ps1"
# or manually:
Copy-Item "$env:USERPROFILE\librewolf\chrome\*" "$env:APPDATA\LibreWolf\Profiles\main\chrome\" -Recurse -Force
Copy-Item "$env:USERPROFILE\librewolf\user.js" "$env:APPDATA\LibreWolf\Profiles\main\" -Force
# 3) Restart LibreWolf (about:config already has toolkit.legacyUserProfileCustomizations.stylesheets=true)

install.ps1 auto-finds Profiles/main via profiles.ini and backs up existing user.js/chrome to *.bak-*.

qutefox-minimal quick edit

Top of chrome/userChrome.css (:root): tab/urlbar font, --urlbar-height-setting: 22px, --tab-min-height: 26px, square buttons, tight paddings. Bookmarks + toolbars autohide via the bundled snippet (--uc-autohide-toolbox-delay: 500ms, --uc-toolbox-rotation: 82deg) — raise the delay if the bar hides too eagerly.

Betterfox

user.js:15 is Betterfox 152 (yokoffing/Betterfox). Top of file = FASTFOX/SECUREFOX/PESKYFOX. Personal overrides at // START: MY OVERRIDES (222). Keep toolkit.legacyUserProfileCustomizations.stylesheets=true enabled.
