* fix v150 patches
* screen related patch fixes
* fix juggler issues with 150
* Update grading.py
improved build tester scoring
* fix windows build for v150
- scripts/_mixin.py: switch moz_target from x86_64-pc-mingw32 (no longer
supported in FF150) to x86_64-pc-windows-msvc
- additions/juggler/screencast/HeadlessWindowCapturer.h: typedef pid_t
on XP_WIN; libwebrtc headers (video_capture.h, desktop_capturer.h)
reference pid_t which is POSIX-only
- patches/anti-font-fingerprinting.patch: include mozilla/dom/Document.h
in gfxTextRun.cpp; on Windows it is not transitively included so
doc->GetInnerWindow() failed with "incomplete type 'Document'"

Replace the userspace lock-file scan + random-jitter retry loop with
Xvfb's own -displayfd mechanism. Xvfb scans up from :0 and atomically
binds the first free X11 socket (kernel-mediated, no userspace race),
then writes the chosen display number back through an inherited pipe.
This eliminates the duplicate-display race that occurred when many
camoufox processes started concurrently and all observed the same set
of free display numbers before any of them bound.
Adds a 10s read timeout on the displayfd pipe so a hung Xvfb fails
fast instead of blocking forever, and adds tests covering single
launch, idempotent get(), 50 concurrent reservations with uniqueness,
and post-kill display reuse.
* Add system-ui font spoofing patch
GetSystemUIFontFamilies() now reads navigator.platform from MaskConfig
and returns the appropriate system font (Helvetica for macOS, Segoe UI
for Windows) before falling through to LookAndFeel::GetFont. Fixes the
CreepJS headless.systemFonts "Sans:Linux" leak when spoofing macOS from
Linux.
* Add patch verification test for system-ui font spoofing
Tests macOS and Windows presets: launches Camoufox with a fingerprint,
measures canvas text width with unquoted system-ui, asserts it matches
the expected system font (Helvetica / Segoe UI).
* Rename test to match patch naming convention
tests/patches/ files should mirror patch names, not use dated prefixes.
* Add config_overrides param to generate_context_fingerprint()
There was no clean way to override config values (like disabling font
spacing perturbation with fonts:spacing_seed=0) because init_script is
rendered inside generate_context_fingerprint() — by the time the caller
gets the config dict back, the init_script string is already baked.
config_overrides is applied after all config building (preset/seeds/
timezone/locale) but before init_script rendering, giving callers a
clean override point without touching the preset (which represents
real device data, not perturbation config).
The longer-term fix is separating config building from init_script
rendering so callers can modify config and re-render. config_overrides
is the minimal API addition that unblocks the use case without that
refactor.
* Rename test to match patch naming convention
When using Xvfb-backed virtual display, override Wayland env vars
(GDK_BACKEND, WAYLAND_DISPLAY, MOZ_ENABLE_WAYLAND) so Firefox/GTK
honors DISPLAY and reliably uses the X11 virtual screen.
closes#575
Without FONTCONFIG_FILE, fontconfig loads the system's /etc/fonts/fonts.conf
which includes system font directories. This means system fonts leak into the
rendering pipeline for fallback glyphs (emoji, CJK, etc.), even though the
font enumeration whitelist hides them from JavaScript. The result is
environment-dependent font metrics that differ between machines with different
system font packages installed.
Generate a runtime fontconfig at ~/.cache/camoufox/fontconfig/ that resolves
the bundled font directory absolutely (the bundled fonts.conf uses
prefix="cwd" relative paths which break under Playwright), and point
FONTCONFIG_FILE at it.
The else branch in _build_init_script() reads the system timezone via
Intl.DateTimeFormat().resolvedOptions().timeZone and stores it via
setTimezone(). When geoip resolves a different timezone (set later via
CAMOU_CONFIG/launch_options), the storage value from the init_script
takes precedence — workers read the wrong timezone and the C++ MaskConfig
fallback (PR #546) is never reached.
Fix: only call setTimezone() when an explicit timezone value is provided.
When omitted, timezone propagation is handled entirely by the C++ side
(SetNewDocument + TimezoneManager::GetTimezone MaskConfig fallback).
Companion to #546 (Fix worker timezone leak when using geoip/proxy).

Allow callers to inject pre-resolved timezone/locale into the
fingerprint before init_script generation. When provided, these
take priority over preset data.
In launch_options(), use setdefault for geoip timezone/locale keys
so that values pre-set via generate_context_fingerprint() aren't
overwritten by geoip resolution.

* feat: cross-process fingerprint storage via Firefox Preferences API
Replace RoverfoxStorageManager's per-process static HashMap with Firefox's
built-in Preferences system. Values stored as CString prefs under
"roverfox.s." namespace, auto-synced to all content processes by Firefox.
Content processes can't set prefs directly (ENSURE_PARENT_PROCESS), so a
single IPDL message (RoverfoxStoragePut) routes writes through the parent.
Same public API — all 10 dependent patches require zero changes.
Removes dom.ipc.processCount=1 from camoufox.cfg. Firefox now uses
Playwright's default multi-process model (fresh process per page) with
fission enabled, while fingerprint values remain accessible everywhere.
* fix(cross-process): hunk headers and build fixes
* fix(storage): add local write-through cache to RoverfoxStorageManager
* fix(storage): add sync IPC read fallback for cross-process fingerprint propagation
* fix(storage): add NS_IsMainThread guard to sync IPC fallback - prevent crashes
* fix(storage): sync IPC + pref whitelist for cross-process fingerprint sync
* feat: full documentation update, speech voices generated per context and BrowserForge primary fingerprint generation method for global and per context.
* fix: Direct3D NVIDIA GTX 980 renderers incorrectly appearing on mac because of duplicates
* Update .gitignore

- Removes the old data directory if Camoufox was installed before 0.5.0
- Fix messy sponsors segment & add repo status info at the top of the README
- Add camoufox/camoufox org as fallback
- Remove (experimental) next to the GeoIP by daijro source
- Format
- Rewrite `camoufox version` to show storage/path info and more python packages
- In camoufox active/set, show active channels. Fall back to original/stable if none is set
- Remove config files in `camoufox remove --all`
- Spoof the camoufox python library version in UI debug mode
- Fix scrollbar always showing on windows
- Other UI cleanup
This allow to pass to Camoufox library the executable-path
from the cli test command allowing to use a camoufox from a different
folder during development.
Example:
python -m camoufox test --executable-path="/tmp/camoufox/camoufox-bin"
If an exception is raised in the synchronous api during the setup, super().__enter__ has been called but super().__exit__ will not get called, leading to asyncio runloop exceptions further down the line if one tries to create a new context. This commit catches the exception in order to clean up the super().__exit__ calls before reraising.
