I noticed that the new forums are using HTTP rather than HTTPS for some of its connections.
Some cases might be inevitable (such as maybe when users embed from websites that do not support HTTPS?). But I just checked and it seems most of the HTTP connections are made to http://schema.org and http://data-vocabulary.org, both of which seem to support HTTPS.
Are these loaded by WaniKani? Or are those URLs inherited from Discourse? If possible, maybe they’re worth upgrading to a secure connection?
Yeah, I’m not sure what my computer had been smoking, to be honest. It reported “some elements” not being secure, but after a while (and of course, after I had posted about it) even Firefox stopped reporting them (and they are now no longer reported).
So, either the problem fixed itself, or there was never a problem and I was involuntarily spreading FUD.
Either way, this seems done. Sorry for the fuss!
The URLs that I thought might be responsible are some links to schema.org and data-vocabulary.org, but those links are still there and my browser no longer complains, so I guess they’re fine.
FWIW: The only thing I’m running that messes with this page is the userscript with indicators for lessons and reviews.
