This evening I faced a really annoying bug: while able to exit Family View by entering my PIN in
Steam.exe, I could not do so when trying to access the Steam website.
I simply could not pass the page "Adults, enter your PIN below to exit Family View." Neither with Chrome nor Firefox: the input field just silently ignored anything I typed in, and the "Submit" button stayed un-clickable.
$('steam_parental_password_box').value = '<your-4-digits-pin>'; SubmitForm()
