The first TVs running Firefox OS are now on sale. Mozilla announced this morning that six models of Panasonic TVs running its new OS are starting to ship in Europe, with global availability arriving in "the coming months." It's hard to actually find the TVs online, but the two models that did turn up — the 50-inch CX700 and the 40-inch CX680 — were selling for £999 (around US $1,570) and £791 (around US $1,240)
