Let’s say you want to give Firefox OS — the mobile operating system made by the same people who make the browser — a try.
Until now, that’s meant one of two things: buying one of a small handful of early Firefox OS devices or hacking your existing Android device to pieces to try to get it running.
That’s starting to change today. Mozilla is releasing a “preview” build that runs within Android to give you a taste without any real commitment required.
The catch? They are shoehorning an OS on top of another OS, so the two might interact strangely sometimes — particularly at this early stage. For example, Mozilla says Android’s back button can cause some weird bugs at times.
But fret not: if it’s too buggy or you’re just not feelin’ it, just remove Firefox OS as you would any other launcher, and you’re back to square one.
