- Add profile_dir= kwarg to InvisiblePlaywright (sync + async).
Maps to firefox.launch_persistent_context(); returns a BrowserContext.
Cookies / localStorage / extensions / cache / prefs all persisted.
- Drop the firefox-4 era workaround that filtered locale + timezone_id
out of the persistent kwargs. firefox-5 ships the C++
docShell.overrideTimezone IDL method (50 LOC patch in
docshell/base/nsIDocShell.idl + nsDocShell.cpp, see patch.md
section 19 in feder-cr/invisible-firefox), so per-realm overrides
land without crashing the launch handshake.
- Bump BINARY_VERSION firefox-4 -> firefox-5.
- Sentinel unit tests added: persistent kwargs MUST include locale +
timezone_id (defends against re-introducing the workaround) and
must NOT include timezone_id when timezone="" is the "host TZ" sentinel.
Validation: smoke test against the local firefox-5 build, persistent
context UP in 21s (was 180s timeout), Intl.timeZone == Europe/London,
hardwareConcurrency / screen / DPR / locale all reflect the PIN.
