- Timeline from macOS unified log
15:35:26 Previous helper instance (pid 1697) exits with the previous Firefox session (exit status 0)
15:35:34 Firefox restarted (pid 1727)
15:35:34 – 15:43:18 NO log entries at all for PasswordManagerBrowserExtensionHelper:
macOS records no launch attempt, no sandbox/TCC/code-signing denial
15:43:18 Helper finally launched (pid 1855, appName "Assistente di Estensione Password (Firefox)");
AppSandbox, LaunchServices check-in and TCC all succeed within ~100 ms;
TCC treats the helper as its own responsible process (disclaimed),
and it holds com.apple.private.tcc.allow for kTCCServiceAppleEvents
=> ~7 min 44 s delay between Firefox start and the first successful host launch.
During that window the Browser Console shows repeated
"Failed to launch process ... subprocess_unix.worker.js :: spawn :: line 398 (NS_ERROR_FAILURE)",
but nothing reaches macOS. The failure therefore seems to happen inside Firefox's
subprocess/spawn path (e.g. posix_spawn setup/attributes) rather than in macOS
permission checks. Once spawned, the host works normally.
(Earlier TCC Apple Events denials concerned com.apple.SafariPlatformSupport.Helper
and appear unrelated.) Logs attached: console export, tcc-firefox.txt, helper-avvio.txt.
