FileAPI reads from local storage (it is still covered by cross-origin 
protection; 
https://developer-new.mozilla.org/en-US/docs/Using_files_from_web_applications). 
You mean FileReader and XMLHttp, right? See 
http://hacks.mozilla.org/2012/02/saving-images-and-files-in-localstorage/ for 
an exaplanation.

OTOH, it is apparently possible to store files (as type blob or file) in 
IndexedDB without conversion to JSON 
(https://developer-new.mozilla.org/en-US/docs/IndexedDB, 
http://hacks.mozilla.org/2012/02/saving-images-and-files-in-localstorage/, 
and 
http://hacks.mozilla.org/2012/02/storing-images-and-files-in-indexeddb/), which 
stores files locally (outside of JSON storage) and should have virtually 
no limits on size.

If you have anything to test, I am willing to help you to test it with 
Firefox (I am using Nightly/Aurora branch, so we should be pretty close 
in terms of capabilities) so that we don't have yet another proprietary 
Chrome-only website.
