Hours after LG unveiled its webOS-powered smart TV interface at CES, Panasonic has spilled the beans on its own mobile-inspired TV plans — announcing a partnership with Mozilla to use the latter’s Firefox OS (FFOS) and open Web standards ethos to open up the living room’s primary screen.

Firefox OS can currently be found cooling its heels on some low-end phone hardware — mostly in Europe and developing markets in South America. The HTML5-based mobile OS has a mountain to climb in competing with the dominance — and reach — of Google’s Android OS. So Mozilla seeking to push it beyond mobile hardware to expand the ecosystem’s reach makes some sense.

Whether the FFOS interface is going to be compelling enough to bag Panasonic smart TV buyers at the expense of other offerings, or for developers to rally behind an open platform banner for building TV apps and integration remains to be seen.
