Two out of three so far of those links lead to blank pages, one all black the other all white, using Firefox on Ubuntu here on laptop and having already just rebooted due to browser having locked up machine already on last browsing session.

Sites nowadays offload so much work onto browser machines that are much larger and faster than those that used to easily allow a few pages of tabs 30-50 tabs of wikipedia pages due to wikis referencing other pages so often when researching etc, that despite higher and higher end machines browsing keeps getting far too much load no matter how advanced the machine.

I doubt whatever code that all black page and all white page are trying to perform on my browser is helping that situation any.

Finally now after typing all that at least the links tree page displays.
