I've been using "3DF33D.TV" to upload and share 3D still and videos. 

The site uses WebGL / HTML5 and I was defeated (on my phone) by an apparent lack of WebGL support in Android.

It turns out Firefox for Android supports WebGL, but you have to turn it on. It's off by default.

To turn it on, enter "about:config" in the address field in Firefox on your phone. 
Then filter for "webgl" and set "webgl.force-enabled" to "true". 

From that moment forward, webgl content will work on your Android phone in Firefox. 

You'll need a fast phone....but it's better than black squares that don't let you see anything at all.
