Description

[Guilherme Lima]

This bug was filed from the Socorro interface and is 
report bp-9c1760ea-e05a-4f9a-9b25-959e52141219.
=============================================================
Firefox 35 (Beta) crashes on the test "conformance/extensions/webgl-depth-texture.html" from Version 1.0.4 (beta) of the WebGL Conformance Tests.

On Firefox 34 the test fails (68 of 72 passed)
    failed: gl.getParameter(gl.DEPTH_BITS) should be >= 16. Was 0 (of type number).
    failed: gl.getParameter(gl.DEPTH_BITS) should be >= 16. Was 0 (of type number).
    failed: gl.getParameter(gl.DEPTH_BITS) should be >= 24. Was 0 (of type number).
    failed: gl.getParameter(gl.STENCIL_BITS) should be >= 8. Was 0 (of type number).


On Nightly the test fails (69 of 72 passed)
    failed: gl.getParameter(gl.DEPTH_BITS) should be >= 16. Was 0 (of type number).
    failed: gl.getParameter(gl.DEPTH_BITS) should be >= 16. Was 0 (of type number).
    failed: gl.getParameter(gl.DEPTH_BITS) should be >= 24. Was 0 (of type number).

I don't have Firefox 36 installed to know what happens there.

Firefox 36 crashes as well.

¡Hola Guilherme!

FWIW https://www.khronos.org/registry/webgl/sdk/tests/conformance/extensions/webgl-depth-texture.html gives the following failures on 37.0 but it doesn't crash:

FAIL gl.getParameter(gl.DEPTH_BITS) should be >= 16. Was 0 (of type number).
FAIL gl.getParameter(gl.DEPTH_BITS) should be >= 24. Was 0 (of type number).

Is that a separate bug or this one?

¡Gracias!

This bug was about the crash.
Just tested 36, 37 and Nightly, and none of them crash. So this bug is invalid right now.

I get the same failure on all of them, though: FAIL gl.getParameter(gl.DEPTH_BITS) should be >= 24. Was 0 (of type number).

But from what I've seem, Mozilla developers know that Firefox have a few failures and have been fixing them when they're important enough. Also, most of the bugs are ANGLE bugs.
