• xul.dll in FF 139 needs more fixing. firefox.exe (x86), too. Work in progress :(
• original xul has sufficient methods in kernel32:
  AcquireSRWLockShared, GetConsoleOutputCP, GetCurrentApplicationUserModelId, GetCurrentPackageFullName,
  GetThreadGroupAffinity, K32GetPerformanceInfo, K32GetProcessImageFileNameW, K32GetProcessMemoryInfo, K32QueryWorkingSet,
  PowerClearRequest, PowerCreateRequest, PowerSetRequest, ReleaseSRWLockShared, ResolveLocaleName, SleepConditionVariableCS, TryAcquireSRWLockShared, TryEnterCriticalSection.
• xul.dll and firefox.exe are copied from other project, for now.
