Do you have link to profiling instructions for Linux that work with Mozilla?
The file is 2MB, it is a standard part of every gnome distribution. It
is in the gnome-mime-data-2.4.2-1.rpm.
I can mail it to you.
I know that Mozilla is not an editor and I don't expect it to act like
one. But on the other hand a user shouldn't be able to click around
the files on their disk and lock moz up.
Is this a DOS vulnerability, can a remote site convince Moz to load a
file even if the site can't read it?
