I'm happy for Mozilla to keep shuffling UI components around - if it gets them more users then that's good, and it's vital that Mozilla be willing and permitted to take risks, instead of always being a step behind in every aspect.

For instance, FirefoxOS seems to have been a failure, but most longshots are a failure, and if you scrimp on long shots then you end up like Microsoft, realizing that some kids these days don't even have a laptop and their phone sure as hell isn't running Windows. So I'm fine with more FirefoxOS-like projects.
