We have a basic registration jsp with fields for First name, Last name, Email-id, Password and Confirm password. To disable suggestions in controls we tried autocomplete="off" in form and in individual controls, suggestions were disabled for First name and Last name, but for Email-id suggestions are still coming. This is the code
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<c:set var="contextPath" value="${pageContext.request.contextPath}"/>

We tried the above code in plain HTML but the effect was same
<!DOCTYPE html>
<html lang="en">

<body>
<div class="container">

<div class="form-group">

<div class="form-group">

We tried How do we control web page caching, across all browsers? but still it is not working, then we assumed like it might be the username so we changed the field to
<input type="text" name="something" class="form-control" autocomplete="off" placeholder="Something">
Still suggestions are coming for the field.
If suggestions are disabled for first two fields why it is not done for Email-id?
PS : Browsers used Mozilla Firefox 68.0.1 and Chrome 75.0.3770.142
