It doesn't, hence why I think we should be consistent and call them all 
"URL". My point is that while I can understand that we can't change 
Document.URL, if we decide that consistency with something else is more 
important for one API, e.g. "File.url", then we really have no excuse for 
being inconsistent with new APIs as well.

I would have assumed uppercase, but I knew of Document.URL.

In practice, though, the vast majority of APIs are learnt through 
tutorials and documentation and visual presentations, surely. I don't 
remember ever learning one aurally (notwithstanding someone telling me 
what to type over my shoulder, but then they'd specify the case). So I'm 
not convinced this is a convincing argument either way.

That doesn't really answer the question.

These results seem inaccurate.

I used these two test files to test the 'storage' event:

It seems WebKit has a 'uri' attribute, and Opera has a 'url' attribute.

Firefox doesn't support <body onstorage>, but using 
window.addEventListener() shows it has a 'url' attribute also:

So we have




I don't know where to go from here. WebKit or Opera implementing File.URL 
or renaming StorageEvent's attribute to URL would be a clincher. Right 
now, Jonas does have a convincing argument in saying that, short of 
Document.URL, Gecko's platform offering is more consistent.
