WebGL troubleshooting, getting (hopefully) webGL to work on your system/browser
How can I enable WebGL in my browser?
Sometimes the browser sets webgl to disabled, for certain video-card and systems, outdated video-drivers and security reasons. Some videocards are blacklisted (since sometimes they would give bugs in certain situations), although they still might work fine. (Although changing the browser flags/settings can sometimes result in enable/run WebGL on blacklisted/older video-cards).
Note on changing settings/flags; use them at your own risk! If it's not working after changing the settings, better restore them back to there original settings.
Also make sure you got the latest video-drivers for your current video-card, sometimes webgl is disabled if you use older video drivers.
Currently firefox seems to run WebGL fastest (v 27.+) on my current system.
Chrome a littlebit slower at the moment. (somehow in the recent build(s) (v 33)+ the performance went down a lot, while before it was faster then firefox)
IE 11; no experience on that yet, can't install it on my current system. (and not sure IE messes up the .collada file-output like it uses to do on older IE versions)
Older IE versions, no proper support for WebGL, and the collada file-output would be all messed up.
Safari seems to have no support for webgl on windows at the moment
Opera - latest build seems to have disabled webgl for my system? Some older Opera builds I had before, WebGL worked fine then.
I read Firefox has webgl support, (my old laptop running Lubuntu; still can't run it. since it got a very old graphic card, So haven't much experience on Linux yet.)
Opera (12?) seems to have support as well on ubuntu?
opera:config -> user prefs -> enable hardware acceleration and enable WebGL set to 1 Works for me (Ubuntu/Opera 12.16) .

In Safari, open the Safari menu and select Preferences.
Then, click the Advanced tab in the Preferences window.
Then, at the bottom of the window, check the Show Develop menu in menu bar checkbox.
Then, open the Develop menu in the menu bar and select Enable WebGL.

WebGL should work on some systems/video-cards
troubleshooting: Check in chrome://flags and see if "Disable WebGL" flag has been set. Also, take a peek at chrome://gpu and see if it's showing any messages indicating why WebGL may be disabled. (via stackoverflow link)
On my old little eee-pc notebook (win-xp/intel video-chip), WebGL was not working in chrome, but when Enable the setting 'Enable WebGL Draft Extensions' it started to work?!
Type in the url bar chrome:flags and search(ctrl-f) for WebGL settings. (use at own risk)
