On My nexus 7 it's really slow. Staring any application takes ages compared to times that ParanoidAndroid does it. Start-up time with Foxfood is noticeably longer than PA, actually I got bored waiting. 8 minutes and counting... It's not possible to stop it and go back to android launcher. There is an updater built-in. UI looks better than my Android, there is no theme changer, so it's a no-go for me. It provides access to applications from Android, but icons are HUGE. On N7 I have 3 icons per row (you can change it to 4, but it's still ugly), so they're really ugly and pixelated. Settings are pretty nice, it looks like something between iOS and standalone Android 5. It didn't fully replace my android UI, as the bottom bar with back, menu, recent is still visible, but pressing back doesn't do anything, instead back button is placed in top left. Not every application has the button, contact settings doesn't have, so I had to restart FirefoxOS to go back to main menu. Also I still see Android heads-up notifications from VPN reconnecting. Doubled. There are a few unnecessary UI-fireworks, which I would like to disable, but can't see any settings about UI. I think battery consumption is big as well, in several minutes of testing I lost 11%, which normally I use 6%-10% in 1.5h. It's good, needs a lot of polishing, and it's getting somewhere. I listed only disadvantages here, but it looks nice, their own UI is clear and consistent, better than android, everything what comes from FxOS runs very smoothly. It's 7/10 for a developer preview package. When those things improve in the future, I will be happy to replace Launcher3 with Foxfood.
