Link inside: do not click:
Website contains 60mb of weblinks and is written in html. I understand it should take some time to 'load' but this freezes Palemoon 28.4.1 64-bit for Linux on a desktop for 14 minutes, haven't tested longer and a force quit is required with a session restore on my equipment. My internet speed is 16Mbps.
I've tried archiving it on 'archive.org' and even there it caused my browser to sporadically freeze. It did create a snapshot, but trying to visit it just times out archive.org.
The 'archive.today' service just times out after 5 or so minutes.
Since it's just html i wonder why there is this reaction, shouldn't above the fold load and then slowly load what's below the fold? Obviously sites like this are a rare occurrence, but it seems something changed where processing sites like this has become a problematic issue. It makes me question whether if this could be exploited on palemoon users that could lead to the same issue where the example trick was done where a large amount of divs in CSS could restart apple devices.

No, because that's not how web pages are normally laid out. It does display what is above the fold but the continued loading and repainting will simply swamp the layout engine and kill responsiveness until it is done. This is because you are creating a huge number of DOM nodes to display all the links (which isn't the case for say, just text) and if something grows beyond 50k DOM nodes, you'll start to severely impact performance.
On top, there is a rendering limit to how high any one element (be it a paragraph or even the body) can be -- and beyond that it will just stop rendering and display black.
This is all because you hit hard limits for the design scope of a browser.
If you want to display huge data in a browser, you have to be smarter about it.
