On My nexus 7 it&#x27;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&#x27;s not possible to stop it and go back to android launcher.<p>There is an updater built-in. UI looks better than my Android, there is no theme changer, so it&#x27;s a no-go for me.<p>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&#x27;s still ugly), so they&#x27;re really ugly and pixelated. Settings are pretty nice, it looks like something between iOS and standalone Android 5.<p>It didn&#x27;t fully replace my android UI, as the bottom bar with back, menu, recent is still visible, but pressing back doesn&#x27;t do anything, instead back button is placed in top left. Not every application has the button, contact settings doesn&#x27;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.<p>There are a few unnecessary UI-fireworks, which I would like to disable, but can&#x27;t see any settings about UI.<p>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.<p>It&#x27;s good, needs a lot of polishing, and it&#x27;s getting somewhere.<p>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&#x27;s 7&#x2F;10 for a developer preview package.<p>When those things improve in the future, I will be happy to replace Launcher3 with Foxfood.
