Firefox loses path of File Input control

I have a File Input control in my form. Using JavaScript, I try to retrieve the full pathes file name of the user's selection. In fileInput.value, I can see (for example) C:\SomeFile.txt. But, the very next line I try to extract that value, like this:

var FullPathFileName = fileInput.value;

In FullPathFileName, I get only SomeFile.txt.

Using FireBug, I hover over that line of code. Hovering over fileInput.value, it shows the full path. Hovering over FullPathFileName, it shows only the file name.

Why does this happen, and how can I stop it? I really need the fully pathed file name.

This is a security restriction, so as not to expose the full path on the filesystem to javascript. It prevents javascript on websites from gaining potentially sensitive information from filesystem paths.

See: Bug 143220 - [FIX]Script can get the value of a file control, including the path (#c49 #c50)
