Security warning on the website

[DennisClark]

When I click on the Ecma Technical Committee 54
link on the https://tc54.org/ page I get the following security warning from Firefox. No idea what to do about it.

Warning: Potential Security Risk Ahead
Firefox detected a potential security threat and did not continue to www.ecma-international.org. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?
The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.
