I do get the warning using the same Firefox version on Windows.

Note that the link in the article is mangled. The link text is <https://no-sct.badssl.com/>, but the actual href points to <https://certificate.transparency.dev/useragents/>. Your comment has the correct link which gives the warning.

Thanks for the correct link! It doesn't trigger the warning on the latest Firefox android though :(

Thanks for flagging this - I've updated the post to fix the link
