64-bit SeaMonkey 2.49 (based on Firefox 52.0 release) on 64-bit Lubuntu 14.04. Hardware is a MacBook Pro 9,1. I'm using Intel graphics.

This game worked well in SeaMonkey 2.46. In 2.49 it's just a black screen. Sound works fine though.
Likewise, this just gives me a black screen with sound - https://s3.amazonaws.com/mozilla-games/ ... arden.html
This occurs even in a new, clean profile. Nothing I've tried within SeaMonkey 2.49 makes any difference.
Now, if I run SeaMonkey in a firejail x11 sandbox, or if I set the environment variable LIBGL_ALWAYS_SOFTWARE=1, the game does work. But, well, that's forcing software rendering, and the resulting framerate is...less than ideal, to say the least. And those things don't help at all with the Mozilla link. So that's not a solution.
Oddly, this stuff has no problems - http://www.ibiblio.org/e-notes/webgl/webgl.htm
How to get WebGL working properly again?
(Would upgrading my OS to 16.04 help?)

Re: Black screen for some WebGL
Shouldn't this be in SeaMonkey Builds?
Anyway the game from the first link works for me.
The second one gives me this message.
I'm using Ubuntu 16.04.2 LTS.

The third link is also good.Your browser does not support WebAssembly. Please try with Firefox 52 or newer.

Re: Black screen for some WebGL
@WaltS48 Thanks for checking. That's more or less what I get with HWA forced off (except my error message for the Mozilla link is different - see below).
I probably should have posted exactly what about:support says about my graphics -
I've tried force-enabling both of those last two compositing entries, but no dice.
What does about:support say about your graphics?

Hmm. I didn't hit any problem with WebAssembly. With HWA force-disabled, this is the error it gives me -WaltS48 wrote:The second one gives me this message.

#2 works fine in a Win 7 x64 2.49 SeaMonkey:

Had to enable session cookies or it would just close the tab. The old problem with storage tied to cookie permissions I believe.

Re: Black screen for some WebGL
After some discussion on IRC, we concluded that the problem is likely that my Intel graphics drivers are just too old. So the answer is probably to upgrade my Ubuntu to 16.04. I will try it and report back.

Might be irrelevant, but I happened upon:

Re: Black screen for some WebGL
The upgrade to 16.04 solved this! Thanks all!
