Hello,

In my environment, Run the html code from firefox, Nothing occurred. This code only set a redirection after windows loaded 600000ms.

<html>
	<head>
		<meta charset="utf-8" /> 
        <meta name="viewport" content="width=device-width, initial-scale=1" />
		<title> LongLiveSession </title>
        <script type="text/javascript">
            // window.onload this point
            window.onload = function() {
                setTimeout(
                    function() {
                        location.href = 'Url for redirection';
                    },
                    600000 // 10분
                );
            };
        </script>
	</head>
	<body>
        <h1>LongLiveSession</h1>
	</body>
</html>

All the browsers occurred this error or only in chrome? Close other browser addone to check this situation.

I'm also getting this error, win11, chrome; though its preventing the loading of a twitter widget which embeds public timelines in html

an example of the code it's blocking:

<a class="twitter-timeline" href="https://twitter.com/TwitterDev?ref_src=twsrc%5Etfw">Tweets by TwitterDev</a> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>

I have check this. Since several days, like the last Update of Google chrome to the latest Version, i get this error, too!

Error: Unchecked runtime.lastError: The message port closed before a response was received.

I got this Error on every Sites, which you visit! And the Counter doesn't stop.

I have check this and find following:

1.) Google says, this will happen, because Google Crhome does not allow Croos-Origin.

I have reinstall, check PCs and so... but

2.) Only what will help, is to uninstall the extension "Kaspersky Protection".

3.) You have to check this. Uninstall the Extension: Everything fine again! (Only - no protection...)

4.) So, I think, the Developer-Area has to check this... maybe together with google, because i find every days, more and more People, who got this error. And, not forgot: Noteverybody looks in the console or knows what is "Console" in Crhome...

At Last: Only in Google - Chrome - this happen and only after the last Version ( Since Version: 99 / 100...)

@ the moment:

Deinstall the Extension: "kaspersky Protection" --> No Problem.

I think this thread deserve more attention, it had been showing up in the past couple of weeks (eventually I disabled the extension, just now finding out it still isn't fixed) in the javascript console on every single tab (which I have around 400, the exceptions it throws per second is literally causing performance issues), it literally wasted me 10 minutes trying to disable each plugin (I have around 60) to see which extension is causing this disturbing console spamming bug. I'm currently on Windows 11 21H2 22000.675, Kaspersky Protection extension 2.0.162.0, Brave 1.39.111 (Chromium 102.0.5005.61)

Hi, I'm having exactly the same problem.

I see this message on the console for every tab.

Error is thrown every ~100ms! Yes 10 errors by second!

Its really anoying as a web developer seeing this error counter go up quickly in every tab.

Only solution.... Disable kaspersky protection on chrome.

As far as I remember, I'm seeing this error from a week ago.

I have been waiting for many months for this error to go away. I am a developer and my console is always open. And guess what, that runtime error is always there, counting away endlessly. This is from the Kaspersky extension. So the solution for me is to turn off this extension and suffer decreased online protection. I am wondering will I get a refund on my subscription too? Anyway if anyone knows any competition I am more than happy to try them out.
