…so try to access a file input’s value property in FFX3. What do you get? The filename. What do you get in IE and FFX2? The filename AND the path.
Well, if your script has been relying on this behaviour, you might find yourself in trouble. So far the only solution i found hides in the comments section of this post (great showcase of new functionality on the other hand btw).

To save you the time, you have to do the following:
- go to about:config page
- swear that you wont make any trouble :)
- set signed.applets.codebase_principal_support to true (search for “applet” in the quick search box)

And in your script something like this:

Now whenever you will try to run the onchange script, FFX3 will display a dialog window where you can confirm access to the full file path.
(Sorry about the formatting i am still examining whats the best way to post code in blogger)
