Firefox OS 1.1 is a pre-release version of Firefox OS, first offered to partners for release on October 21, 2013. Its Gecko component is based on Firefox 18 (see Firefox 18 for developers) just like Firefox OS 1.0.1, but with some additional bugfixes and APIs added. This page details the developer features newly implemented in Firefox OS 1.1.

Firefox OS HD support

Since Firefox OS 1.1, there are HD versions available to provide HD support for high-DPI devices. This is mostly just a visual change, dealt with in the same way that you'd deal with other devices of differing resolution, and you'll encounter nothing much in the way of underlying platform differences.

Fixed Firefox OS Issues

  • 817972: [Bluetooth][File-Transfer] Support multiple files transferring.
  • 834672: AppProtocolHandler.js should never throw.
  • 839500: Gaia‘s identity.js opens a browser process that‘s stuck in the foreground. Therefore, if you open the marketplace app, you lose ~10% of available app memory until you reboot the phone.
  • Memory fix for Persona logins.
  • 834773: Using the pick activity and confirming an image for the gallery — app gets hung with no perceived perf for 5–10 seconds
