As an effort to reduce the APK size of Firefox for Android and to remove unnecessary code, I will be helping remove the Honeycomb code throughout the Fennec project. Honeycomb will not be supported since Firefox 46, so this code is not necessary.
Bug 1217675 will keep track of the progress.
Hopefully this will help reduce the APK size some and clean up the road for killing Gingerbread hopefully sometime in the near future.
