Even if we assume that is true, mozilla has already a mobile version that not only works very well but allows for things that the mobile chrome doesn't, the idea that a reskinned chromium would work better than firefox itself is...weird. There are two relevant phone OS's and they're owned by google and apple, both companies have their own browsers, firefox will never get wide default usage on phones regardless of the quality of their mobile browser, which I already believe to be extremely competitive.

There is no winning going down this road for Mozilla other than maybe going the firefox phone route, and we all saw how that went.
