Google-chrome – How to disable data: URIs in chrome

google-chromegoogle-chrome-extensions

I can't stop some people in my family from visiting sites with bad stuff on them but I can try to minimize the damage (and the amount of time I have to constantly take to fix the subsequent problem). Evil data: URIs are causing me major headaches at the moment. Most of the extensions I can find to block specific URIs assume they start with http or https and don't even let me enter the protocol (and so won't block data URIs). The "Simple Blocker" extension seemed to do the trick at first, but not before it lets some things slip through (redirects, popups, etc). Any help on blocking or disabling data: URIs would be very highly appreciated. Thanks.

Best Answer

Web pages/links can no longer open data URIs in Chrome 60+ (late July 2017), Opera 47+ and Edge. Users can still download from them or navigate directly to them from the address bar. A third-party extension is no longer needed.

How to Disable Autofocus on Input Fields in Chrome – Google Chrome Extensions

I've just written script for you:

// ==UserScript==
// @name           Disable auto-focussing
// @author         ComFreek <comfreek at the following domain 'outlook' with the TLD 'com'>
// @description    Disable auto-focussing
// @include *
// @version        1.0
// ==/UserScript==

var maxTime = 3000;
var timeoutInterval = 5;

var usedTime = 0;
var isManualFocus = false;
function check() {
    if (!isManualFocus && document.activeElement.tagName.toLowerCase() == "input") {
        console.log("BLURRED");
        document.activeElement.blur();
    }
    usedTime += timeoutInterval;
    if (usedTime < maxTime) {
        window.setTimeout(check, timeoutInterval);
    }
}
check();


document.body.addEventListener("click", function (evt) {
    if (evt.target.tagName == "INPUT") {
        console.log("MANUAL CLICK");
        isManualFocus = true;
    }
});

document.body.addEventListener("keydown", function (evt) {
    isManualFocus = true;
});

Warning The script will interfere with the user if he immediately starts typing while the script is still operating. This is fixed.

Installation (manual method)

Save the script as XX.user.js (XX can be any string, but .user.js is important here!)
Open the extensions page in Chrome (the URI is chrome://extensions/ as of Chrome v31)
Drag the script from the file explorer and drop it over the extensions page.
Confirm the installation

Installation (TamperMonkey)

My script should work with TamperMonkey according to OP's comment below. Please consult TamperMonkey's manual for further information on how to install my script.
