+### Firefox OS Quirks
+
+The File System API is not natively supported by Firefox OS and is implemented
+as a shim on top of indexedDB.

+* Does not fail when removing non-empty directories
+* Does not support metadata for directories
+* Does not support `requestAllFileSystems` and `resolveLocalFileSystemURI` methods

In v1.0.0 of this plugin, the `FileEntry` and `DirectoryEntry` structures have changed,
