This GIF *appears* "interlaced" in Firefox, as though every other line is
seriously misaligned. The problem is also visible on the mozilla.org site in the
"Developers" graphic there, but it appears more subtle.

Reproducible: Always

Steps to Reproduce:
1. Open Firefox 1.0.1
2. Open that GIF


Actual Results:  
The GIF displays, but with errors.

Expected Results:  
Displayed without errors. =)

And it looks the same in Safari and Opera. Please attach a screenshot.

Dup has screen shot. Looks like the problems from before Quartz image. Reporter,
are your colors set to Thousands or Millions?

Attachment: screenshot of my desktop with safari and firefox open to the same image, showing that the problem is only inside of firefox

Here's a screenshot. The firefox window is behind the safari window; I dragged
the URL from firefox to safari, and it politely opened the GIF - and shows it
correctly. Now, I happen to think safari's UI stinks like hot summer garbage,
but this really is a problem with firefox and GIFs.

To answer L.H.'s question, my G3 iBook is set to "Thousands" of colors.

In trunk of nightly build, because bug245407 (bug239701) did Fix, drawing of the
image is improved. 
But it is not reflected in Branch Build.

So dup of bug 239701?

Comment 9

[Arthur Wiebe]

jrose, can you download a recent Firefox trunk build and try to reproduce using
it instead?
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/firefox-1.0+.en-US.mac.dmg

This is probably a duplicate of 239701 which has been fixed in trunk.

The nightly build has fixed this problem with my .gif.  As it turns out, I filed
a duplicate of this bug report without knowing it.  Better searching next time!
Thanks, Blake. Best.

not, it wasn't (and it won't) checked in into 1.0.x/1.7.x branches.
