I can imagine a few scenarios...

You may have Firefox's Artificial Idiot features enabled, and it may be
trying to preview such links.  I disabled all the AI stuff.  I don't
know how much "safe mode" really disables.

That's an unusual named log entry (it's not just a domain name), though
if you had DNS over HTTPS enabled, I wouldn't expect a local resolver
to get any kind of query.

Even without plug-ins, Firefox has some content-checking features built
into it.

I'd recommend going through its settings (the normal ones, for a
start).  Then maybe some of the hidden from normal sight things in
about:config (search for prefetch in them, maybe search for preview,
too, perhaps disable some of them)
