Details

Mozilla treats 32-bit PNG images (8-bit alpha channel) as if they had
1-bit alpha channel (binary transparency, as in GIF format).
That's more like a missing feature than a bug, but webmasters have been waiting
for ages to get full 8-bit alpha channel support in WWW browsers (binary
transparency model gives jerky pixels on the decal image's edges)
See the URL above, http://sudety/pnghtml/index.html and
http://www.cdrom.com/pub/png/ for more info on PNG and its various transparency
modes.
