The browser has not noised the canvas since #528, and no patch reads canvas:seed (#721). The launcher still drew one on every launch and sent it through CAMOU_CONFIG, and NewContext called a setCanvasSeed that does not exist. They no longer do. For users this changes nothing on any browser since #528: the value was ignored. A config that still passes canvas:seed gets the usual "Skipping unknown patch" notice instead of silence. On a browser from before #528, the launcher no longer turns canvas noise on, which is the behaviour #528 chose. The same audit found more keys declared in settings/properties.json that no patch or Juggler file reads, so setting them did nothing: - canvas:aaOffset, canvas:aaCapOffset - memorysaver, pdfViewerEnabled, webrtc:localipv4/6 - navigator.onLine, navigator.cookieEnabled, navigator.languages - navigator.appCodeName, appName, product, productSub. Firefox reports these constants itself, so fpgen.yml no longer maps them. - webGl:parameters:blockIfNotDefined and its WebGL2 twin test_config_schema now checks this direction too: every declared key must be read by the browser, unless it is listed with a reason. Three are listed: locale:script and navigator.doNotTrack, which the launcher applies itself, and navigator.buildID (#780). The build-tester grading followed the same wrong premise. It tracked canvas collisions as an unfixed per-context leak. A canvas that is rendered rather than noised follows the fonts and GPU, as it does on real machines, so canvas collisions are now counted with the other device-level values. The tribal rule that recorded it as an open question is now a settled one, canvas-is-not-noised, with an automated check. Closes #721. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Mappings of fpgen fingerprints to Camoufox config properties.
|
|
#
|
|
# fpgen (scrapfly/fingerprint-generator) replaced BrowserForge/Apify as the
|
|
# generator. The field set below is the one BrowserForge used to supply -- the
|
|
# rest of what fpgen carries (fonts, voices, WebGL parameters, system styles,
|
|
# permissions, RTC capabilities, audio) is NOT mapped here yet; Camoufox still
|
|
# draws those from its own catalogues. Wiring those through is the follow-up.
|
|
#
|
|
# Shape differences from browserforge.yml:
|
|
# - window geometry is its own `window` node, not part of `screen`
|
|
# - header values are lists
|
|
# - there is no extraProperties.globalPrivacyControl; GPC is a pref Camoufox
|
|
# owns (see utils.launch_options), so nothing maps to it
|
|
# - doNotTrack is deliberately NOT mapped: Camoufox sets DNT from its own
|
|
# config, and a drawn value is stripped unless the caller asked for one
|
|
|

# Spoofing them deadlocks Playwright: setViewportSize resizes the window and
|
|
# then waits for the page to report the size it asked for, and a spoofed
|
|
# innerWidth/innerHeight never changes, so the wait never ends. Camoufox
|
|
# already defaults to no_viewport for this reason (#666); this is the same
|
|
# trap reached through an explicit set_viewport_size() call.
|
|
#
|
|
# BrowserForge hid it by accident -- its Firefox samples carry innerWidth and
|
|
# innerHeight as 0, and _cast_to_properties skips falsy values, so these were
|
|
# never spoofed there either. fpgen reports the real numbers, which turned an
|
|
# unmapped field into a hang (tests/patches/humanize-edge-deadlock.py, which
|
|
# calls set_viewport_size, timed out at 600s in CI).
