I have an form with autocomplete disabled but it does not works and makes the autocomplete to be enabled in firefox and higher version of chrome

<form method="post" autocomplete="off" action="">
    <ul class="field-set">
    <li>
        <label>Username:</label>
        <input type="text" name="acct" id="username" maxlength="100" size="20">
    </li>
    <li>
        <label>Password:</label>
        <input type="password" name="pswd" id="password" maxlength="16" size="20" >
    </li>
    <li>
        <input type="submit" class="button" value="Login" id="Login" name="Login">
    </li>
    </ul>
</form>

When the type is changed from password to text it works in all browser. Can anyone help to solve this issue?
