Based on a web search, https://bogdanz.me/work/diddu.html might be a working mirror of the proof of concept.

It appears to contain a 10MB long UTF-8 mess in both the og:title meta content and in a mailto: link.

I'd guess it's supposed to crash iOS apps by either posting that link if it displays links in a thumbnail element using og:title or otherwise by pasting the huge mailto link contained in the webpage, or perhaps only the e-mail address.

That site caused Firefox 57 (64bit) to lock up on Windows 10...

It is an i7, 16 GB total (7 GB free), and an SSD.

Same for me, except on Windows 7. CPU spiked to 100% and I warmed up my hands with the extra heat :). Closing the tab and waiting a minute or so (the usual thing I do for cpu/memory intensive pages like this) didn't work. I had to completely restart Firefox to get it back to normal.
