We're having issues with the newly released Firefox 17.0.1. Weird "syntax
error" in places that don't make any sense (like line 642 of prototype.js):
Firefox 17 no longer supports the toString function as before:
`toString` for function objects has changed.
> Error: The `toString` implementation for function objects have changed. If
> you are using `eval` or `Function` to change the behavior of 'native'
> functions, it is probably not working correctly in Firefox 17 and above.
Anyone else having this issue? What's the fix?
