Ah, another in the ranks of non-working WebGL. So many things I can't see :(
(I browse via VNC - long story - and I need to claw back as much RAM as possible so Chrome is usable, so I tend to kill the GPU accelerator process since it makes every renderer process use about 75% RAM! But byebye WebGL...)
A very good question :) the reason is partly hilarious and absolutely mystifying (to me at least).
The TL;DR of it is that for some reason I haven't yet identified, using some kinds of electronic equipment affects my ability to focus and think clearly, and replaces whatever clarity I have with debilitating fog and anxiety instead, and the impact is so great this state can last for weeks afterwards in worst-case situations. I've been aware of this since 2008 (when I had a bad reaction to something that forced me off all my computers for 4 years), and it's the reason I can't work or study, because my nerves keep reacting (sometimes somewhat violently) to random bits of tech. :(
I know it's not a screen/display/eye thing, since the device that initially set me off (a PlayStation 2) caused problems even if wasn't plugged into a TV. I know it's not some kind of "electromagnetic radiation sensitivity" thing, because I've been using Wi-Fi for years, I started using Wi-Fi _after_ the PS2 reaction, and I've never had a single issue (no brain fog or other symptoms) with it.
I still can't use PS2s, I still get the same reactions, and I still react to random things. An electronic toll-way (highway) tag (the kind that beeps when it goes under a toll point). Some USB speakers. Multiple graphics cards. Random computers I have to avoid.
And, unfortunately, every LCD I have here. :(
So my ThinkPad T43, which for some random reason seems to be okay, is actually really just my "screen", although obviously I use its keyboard as well. I use it to VNC to an i3-based machine I previously used with the aforementioned LCDs until (eyebrow-raising story short) that PC got turned off and I realized the screens were only the icing on the cake and that the machine itself was also causing a lot of issues. Not sure whether it was switching the PSU or removing the GPU that helped, but I can tolerate it being on now, so that's how I browse. Typing over old+flaky 54Mbit Wi-Fi from upstairs to downstairs (with an amplified Wi-Fi dongle at my end, even! Definitely not an EM/RF sensitivity problem) is great: I was very impressed to find that per-character latency is only maybe 30-40ms, maybe even 25ms. (At some point I hope to measure it with a slow-mo camera, that would be cool.)
But yeah, the not-working and not-studying thing is driving me nuts. (Particularly with health issues involved that are really expensive to treat.... :D The reason I'm using a 12 year old computer isn't really because "it's a magic PC", it's more that I've just never been able to go shopping for anything [else].)
Works fine for me on both FF and Chrome on Linux, as well as both on my phone. It will need WebGL, maybe your drivers/hardware don't support the required version?
