set time out in JavaScript

Because setTimeout() requires your function to be passed as a string or as an anonymous function:

setTimeout(function() { document.getElementById("safeFormec").submit(); }, 100);

Take away the quotes from around your action:

setTimeout(function() {
    document.getElementById("safeForm4d").submit();
}, 3000);

Have you tried removing the function call brackets from the end of this line?

document.getElementById("safeForm9c").submit()

i.e. do this instead:

setTimeout(document.getElementById("safeForm9c").submit, 100)

You’re telling IE to call the results of submit() in 100 milliseconds time, rather than call submit.
