I don't really see how this would prevent Mozilla from shipping a
browser with ASLR. The Tor browser has been shipping a fork of Firefox
built as a position independent executable for ages. It doesn't impact
users because they're either starting it via a .desktop file or the
command-line.

The support for desktop icons in Nautilus is deprecated / disabled by
default with only a hidden dconf preference to enable it. If you really
want to support the workflow of opening up the file manager, navigating
to the binary and double-clicking it then using a wrapper script is a
quite obvious solution.


Obviously, some users are running into it (

had to be backed out.
