Every Android 2.2+ device (*) supports WebGL with Firefox ;-) and the slow-WebGL bug is getting worked on ( https://bugzilla.mozilla.org/show_bug.cgi?id=728524 ).
(*): except for certain versions of the Adreno driver that had to be blacklisted. And yes, ARMv6 support is coming.So what's the scoop? Does it support webgl?
