Answer
You are using Web SQL Database, which is not supported by Firefox. Also, the specification is abandoned by the W3C.
Have a look at IndexedDB (caniuse) instead. There is also at least one shim to make IndexedDB work in browsers that only support Web SQL Database.
The code "works" in this updated fiddle on Android Browser 4.1.2.
