Why does "unfurl" work in #1 & #2 but not in #3?

For all the people using FreeBSD as their primary desktop.

I love FreeBSD, really I do. I love its rock solid stability (my Linux installations seem to always have weird quirks from time to time), performance, directory consistency, relatively simple setup, and of course The FreeBSD Handbook. I've dabbled with it off and on for years, but have never...

Or am I missing something?
 
Thanks, I think there is some kind of a delay at work. When preparing my message I didn't see the link "unfold"; even after posting and trying several times thereafter it stayed the same. Also tried another browser: still unfolded.

Now I can see #3 unfolded; but, at this moment, I still don't see the unfurl unfolded in my other message: this one
 
I found a guy having the same problem and he says he needed to remove the url-tag for unfurling:

XF 2.1 - url unfurl question

Hello when my users post a url into a media or forum comment it does not unfurl but rather produces a link, unless I remove the link no unfurling happens. How can I change things so that no link is created and the unfurling occurs. Thank you

Yes, that helped. I'm still not sure what exactly prohibits it and what makes it switch on. However, what counts is that others seem to see it, always. Fiddling with removing and then adding the [url]-tags, sometimes with clicking on "Preview", seems to do the trick.

My suspicion is that is has something to do with the (auto)fetching of the content (from the specified url) that is shown in the unfolded link and with browser caching (the latter has the tendenacy to behave in unexpected ways when you least expect it ... ).
 
As far as I understood the function the actual "unfurling" happens on the client, it's not done server-side. It's your local browser that fetches and renders that preview.
