You can try setting autocomplete="off" as an attribute on the <input type="text">. Note that this isn't a standard attribute though, and will break HTML validation.

this is a browser-issue

In Firefox: Extra -> Options --> Privacy --> Remember search and formhistory (or something like that, I have Firefox in Dutch)

For IE: http://www.computerhope.com/issues/ch000604.htm

Try this

<input type="textbox" id="myTextBox" autocomplete="off" /> 

For an asp textbox

<asp:TextBox AutoCompleteType="Disabled" runat="server" ID="myBox"></asp:TextBox>

See autocomplete attribute

The autocomplete attribute applies to the text, password, select, textarea, date-related, time-related, numeric, email, and uri controls. The attribute takes two values, on and off. The default, when the attribute is not specified, is on.

Set the autocomplete attribute in the form element to "off". Said attribute is not standard, but should work on most browsers. See this
