Add this code after prototype.js =). Also this code replaces FF 3.5
Native JSON.stringify with ES compatible...
It breaks compatibility!
delete String.prototype.toJSON; //! deleting this properties required
to save FF 3.5 Native JSON.stringify
delete Array.prototype.toJSON; //!
delete Number.prot

May I ask you about localStorage?
I want to update some property, but no space left on device and
FireFox throws error "NS_ERROR_FILE_NO_DEVICE_SPACE",
so "localStorage[property]" stays unchanged.
try{
localStorage[property] = value; //throws
"NS_ERROR_FILE_NO_DEVICE_SPACE"
}catch(e){

I use "small" (40 lines of code) storage class, that uses cookies or
localStorage.
IMHO, userData and databases not so usefull:
IE userData behavior relies on DOM.
database works in webkit, which supports localStorage.

You're right, `hasOwnProperty` can be useless, and
