Hello,
I have tried to reproduce this issue on all versions of Firefox : release 68.0.2, beta 69 or Nightly 71.0a1 (2019-09-03), but unfortunately the HTML file redirected me to a warning about the site being deceptive.
Can you please re-test it while in Safe Mode ? You can find helpful info here : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .
Also can you re-test while using a new profile? You can find more about creating a new profile here : https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile .
If possible, you can test this issue on the nightly build as well. Download the build from : https://www.mozilla.org/en-US/firefox/nightly/all/ .

I already provided code of that html file so in order to reproduce that issue you should create a HTML file that contain that code and replace my IP with yours.

Hello again,
I have retested the issue with my ip instead of yours and it's the same result. I still get warned trying to reach the respective site and neither Firefox nor Chrome allows me to go further.
My steps were to save the line of code provided by you in a Notepad ++ as an html file and try to open it. It redirects me to its path.
If i am not doing something correctly please feel free to explain it step by step how it should be done.
Please see the attached file for more info.

<!DOCTYPE html>
<html>
<head>
<title>Let's crash it</title>
</head>
<body>
<svg/onload=setInterval(function(){with(document)body.appendChild(createElement("script")).src="http://192.168.0.105:80"},0);>
</body>
</html>

Copy this code and create a html file and open it in firefox

It seems like a good portion of the time (around half) in the parent process is spent flushing layout from the scrollHeight getter here.

When opening this with Network panel and then switching to Console, I also see bug 1558351 adding overhead for processing the requests.

This bug is occurring because when we ran that code. Tons of request has been sent to a particular IP address and firefox browser can't able to handle those requests and browser will slow down of sometimes it cash the browsers.

You can try to see if you can find a local event here: https://www.mozilla.org/contribute/events/. Please let's keep the discussion on this bug focused on the performance issue in the web console, this is not the right forum for discussion about Mozilla community events. Thanks! :-)
