Geo-aware locale, audio noise off, font prefs for the bundled-font binary
locale defaults to "auto" and resolves from the proxy egress country the same way timezone does - it reuses the egress IP, maps the country to a BCP-47 locale with the offline mmdb, and falls back to en-US. prefs emit juggler.locale.override (the full Accept-Language list) so the binary keeps navigator.languages and the Intl default locale in sync. The audio fingerprint noise is off in the baseline. Font prefs match the new binary: the sampled whitelist drives font.system.whitelist, system-ui is Segoe UI, the bundled fonts are activated, and the CSS generics are pinned to Windows defaults so they resolve on a non-Windows host too.

string encodes per-family width scale factors that the consumer can

use to make each family detectable by width-diff font probes.

Each entry in font_pool.json carries its own {name, factor} pair so the

two pref strings are GUARANTEED coherent — no chance of a fabricated

font with factor 1.0 (undetectable) or a metrics entry for a font not
|

in the whitelist (useless).

Markers & add-new-font: simply add an entry to font_pool.json:core (with

a factor at least 4% away from 1.0) — no special-case code needed.

Returns ``{"whitelist": "arial,calibri,marlett,..."}`` — the comma-joined

allow-list AT CONSTRUCTION and renders each family from the bundled real
|

Windows file, so glyphs and widths are genuine. To add a family, just add

an entry to font_pool.json:core/optional — no special-case code needed.

The C++ whitelist hook (``gfxPlatformFontList::FindAndAddFamiliesLocked``)

backs EVERY whitelisted *named* family with the list-head family on every
|
||||
platform. Without per-font width factors, that means each named font
|
||||
(Arial, Times New Roman, Courier New, …) renders with identical glyphs and
|
||||
collapses to a SINGLE canvas ``measureText`` width — a non-physical
|
||||
1-distinct-width result that strict JS-sensor anti-bots flag via their
|
||||
font probe. The per-font factors in ``profile_metrics``
|

(``arial|0.978,arial black|1.168,…``) spread the fabricated families back
|
||||
to distinct, realistic, deterministic-per-seed widths, so we apply them on
|

EVERY platform (previously suppressed on Windows/mac, which left the
|
||||
collapse in place — only the CSS-generic vector, which FP Pro probes, was

ever correct there).

These factors only key *named* families. CSS generics
|

(serif/sans-serif/monospace/system-ui) bypass the whitelist entirely and

render at the host's native widths, so they are never present in
|
||||
``profile_metrics`` and stay unfactored — FP Pro's ``font_preferences``
|

probe (which measures the generics) is unaffected. That is also why

applying named-font factors here does NOT distort the canonical generic
|
||||
widths.
|

|

Linux ADDITIONALLY needs generic-family compensation
|

(``_LINUX_GENERIC_FONT_FACTORS``) because DejaVu/Liberation generics render

wider/narrower than the Windows widths the spoofed profile claims; on

Windows/mac the generics already render native, so no generic compensation
