Github's response: "... further degrad…
If you've chosen to use a web browser that's forked from an old version of Firefox and isn't aiming for compatibility with modern Web Platform Tests, you're going to encounter a lot of obstacles. The fact that you can't see the server-side code generating the failing client-side code, which you can see, seems like the least of them.

It should be entirely possible to use GitHub with a text-based browser because none of its interactions require anything more than that.
It's sad that I could probably write a more accessible interface in less time and resources, and I haven't even done much in the way of web development, yet dedicated web-developers with uninhibited trendchasing mentality will fuck it up so badly with this constant need for useless breaking changes.
Seriously, fuck this "modern" bullshit.
