Please note that both Firefox and Chrome support BC1, but due to an implementation issue in the code it doesn't work on Firefox yet. (It doesn't test for the "WEBGL_compressed_texture_s3tc" extension.)
-On browsers that don't support BC1, there's a low-quality fallback code path for opaque textures (but no fallback for BC3 yet). Note that the fallback path only converts to 16-bit RGB images at the moment, so the quality isn't as good as it should be.
