I'm not the author.

The html sourcecode shows the content of the table is not served within the page, but is added on page load through javascript by formatting a json requested file. I changed the browser's user-agent to chrome and the same page was served (though the link to git shows it's an static page). My guess is may be chromium is not disabling javascript.

PS: I'm a Firefox user too, I always browse with Javascript disabled by uMatrix (in addition to uBlockOrigin), I only enable it when the web deserves it and leaving disabled third domains js loads almost always.
