I read "mozza", then I "got" the web reference, and immediately disliked it. I don't really understand how moz://a is better than Mozilla, but I don't categorically oppose it either.

New branding is fine but the choice here is a bit more debatable than the examples you point out, where each of the brand names are spelled 100% with the alphabet. In OP, 3 characters in 7 are not letters.

Edit: Maybe Mozilla could have suggested an addition to UTF-8 and used that new stylized character "://"?
