Firefox 14 having broken WebGL on Android is a known issue and a likely consequence of our rushed fennec 14 release process. It's fixed in 15.

No it's not. I get the exact same in beta as well.

Then let's change the bug title to 'Firefox 15'. That's very worrying, I thought 15 was fixed. It's important to identify what fixed it (since it's fixed in Nightly, right) and backport asap. Bisect nightlies?

I can lend you my phone. ;-) Bisecting nightlies on a phone is not super exciting... :)

I'm afraid that this might be much more general than Jelly Bean.... so you might not have to lend me your phone. I'll try.

Hah, yeah, it's only in Firefox 16 that we enabled the canvas mochitests: bug 759221. So Firefox 15 has all canvas stuff completely untested.

Good news: WebGL is correctly working in Firefox 15 Beta on my Nexus S (Android 2.3). So we may hope for this bug to not affect 100% of our users ... maybe even it's JellyBean-only.

This was first fixed in the July 16 nightly. Last bad Nightly: July 15, 57abb5f70e01 First good Nightly: July 16, 4cffe2b37d0c pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=57abb5f70e01&tochange=4cffe2b37d0c -> this is almost certainly fixed by Oleg's WebGL compositing patches from Bug 728524. These are too big to backport. Since WebGL is working on at least _some_ phones in Firefox 15 (at least my Nexus S / Android 2.3) I suggest we leave it there. The July 16 Nightly is still Fennec 16.0a1 so this is fixed in Aurora now -> Firefox 16. So the bug is limited to Firefox 15 alone.

WebGL works on newer versions of Fx.
