It is still rejecting some files with "invalid distance too far back"
which were acceptable to zlib-1.1.x.  This is a problem because IE accepts
PNG files with this error, so it is perceived as a bug in Firefox to
reject them.  Can the ~DEFLATE_STRICT behavior be expanded to accept
these files?  Applications built with the CollosseumBuilders library
are generate them.  There is a sample PNG file at
http://www.graphicsmagick.org/users/glennrp/mozilla/bug327389/default.png

I realize that it is a lot of magnanimity to ask, to accept invalid
datastreams, and I won't ask you to do it if it opens a vulnerability.
But all the same, uneducated users only see it as a bug in zlib or firefox.
