Extension Metadata

About this extension
Educational HTML sandbox in the form of a private browsing new tab.

MAKE SURE TO ENABLE THE EXTENSION TO RUN IN PRIVATE WINDOWS!

After, access the browser inspector using CTRL-SHIFT-I or in the toolbar and modify the HTML elements INSIDE the document INSIDE the iframe known as "contentFrame." The changes will save with local storage unlike the actual inspector.

More details in the inspector comments of the new private tab!

THE <script> TAG DOES NOT WORK!! DO NOT USE IT!

There are plenty of HTML tutorials and websites, and HTML is easy to learn!

Default HTML page you start out with, to remind you, the user, to use private browsing more carefully:

<html>
<head>
<meta charset="UTF-8">
<meta http-equiv="Content-Security-Policy" content="script-src 'self' 'wasm-unsafe-eval';">
<style>
#search:focus {
outline: none;
filter: brightness(0.95);
}
#search:focus::placeholder {
color: transparent;
}
</style>
</head>
<body style="height: 100vh;overflow-y: hidden;">
<h1 style="margin: auto; text-align: center; font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;font-size: 69px;color: red;">LOCK IN</h1>
<p style="position: relative; text-align: center; font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;font-size: 21px;">You are <b>NOT</b> seeing regular private browsing page right now</p>
<p style="position: relative; text-align: center; font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;font-size: 34px;">None of your browsing you do here will be gone. So please do not do anything unsavory during this session. Or any browsing session.</p>
<p style="position: relative; text-align: center; font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;font-size: 34px;margin-top: 100px;">You have a life you need to focus on. Override this message using this browser's inspector but do realize that <u>your browsing history may be inspected.</u></p>
<input id="search" autofocus placeholder="Search to your heart's content" style="width: 80%;height: 69px;position: relative;border: black 1px solid;background: white;border-radius: 69px;left: 10%;display: flex;font-size: 47px;text-align: center;font-family: cursive;">
</body>
