> But they can’t say Firefox only supports free and open video formats while still supporting Flash.

Mr. Gruber should be more precise by what he means by support.

Firefox's support for Flash is not like the proposed support for H.264. There is no Flash code in the Firefox codebase, to my knowledge. There is only a generic plugin interface, and there is one dominant, proprietary Flash plugin that Mozilla has nothing to do with (in addition to other less-featured Flash plugins).

What Mr. Gruber seems to be saying is that he wants Firefox to distribute H.264 code with their browser. Either that or Firefox should rely on codecs that may or may not be installed on the underlying system.

In the former case, the analogy is fatally flawed, while if the latter is intended, it should be explicitly addressed.
