I have on my web pages a standard link to do web page validation by W3C.

I don't know when this was changed, but in Firefox 61.0.1 the "referer" 
in "http://validator.w3.org/check?uri=referer" does not pass on the web 
page url anymore, and hence the default web page is always validated.

Internet Explorer still works fine, and so do Opera and Google Chrome.

It is obviously a (security?) setting in Firefox that causes my problem.

Can someone point me in the right direction please? Thanks.

Have you tried changing "http://" to "https://" for the referrer link?

Thanks, that explains a lot. I think that I will change "referer" into 
the full url for my W3C validation.

I maintain someone's website that is completely "https://" and I had to 
use "https://" for the validation link for it to be accepted, but still 
the same problem.

As I already said in my reply to Dave Royal, I will use the full url 
instead of "referer" in this case.
