Firefox vs Chrome WebGL differences - disappearing object

[01miru]

Hi, I just start with WebGL and I have a problem with rendering textures.
In Chrome, everything looks fine but in Firefox nothing appears. What is the cause?
I have enabled support for WebGL in Firefox
Demos from this site work without a problem.

Do you have the Firebug extension for Firefox? If so, can you turn it on and pull up the Console panel to see what errors may be present?

My guess is that it's not working because you're trying to load a texture locally. Browsers treat all files loaded locally as if they are from different domains (cross-domain) and FireFox 5 will error out if this happens.

Can you host your files either through a web host or on your computer through Apache? I'm guessing doing so will fix the issue.

This is the same as the files are on the server. I get this message:

uncaught exception: [Exception... "Failure arg 5 [nsIDOMWebGLRenderingContext.texImage2D]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///C:/Users/miru/Desktop/projekty/cube/build/Three.js :: L :: line 293" data: no]

Well, your screenshots and error messages show that you load images from a local file system (file://), not a server (http://).

What's curious is that it works for you on Chrome. For local files to work on Chrome, it has to be started with --allow-file-access-from-files command line flag.

For Firefox, there is a similar parameter security.fileuri.strict_origin_policy accessible via about:config.

Or, as @chandlerprall suggested, you could run local server: Apache, nginx, or if you already have Python installed, there is trivial way how to serve local files via simple server:

$ cd /home/somedir
$ python -m SimpleHTTPServer

Sorry, my mistake. When loading from server works fine :)
