The FXP (FreeXperia) team of developers have worked wonders with Sony Xperia devices for a number of years now. If you like tinkering with your devices and you’re bored with Android custom ROMs then you might want to try Firefox OS. The FXP team worked in collaboration with Mozilla to support several Sony Xperia devices in Mozilla’s repos.
Firefox OS is a fast and lightweight operating system that FXP says should work extremely efficiently on current hardware. FXP has released Firefox OS builds for the following devices: Xperia Z3, Xperia Z3 Compact, Xperia Z2, Xperia T2 Ultra and Xperia E3. Firefox OS Nightly’s for these devices can be downloaded here.
The good news is that even though FXP are releasing new builds, it is also enabling OTA updates on all devices. Therefore updates will be automatically pushed to you every week. It is worth noting that the current builds do not feature any Firefox OS branding as Mozilla has been quite precious over the use of its brand and logos in any AOSP ROM. Therefore, FXP is using the “Foxfooding” logo for now. If you want to find out more details, click the source link below.
