277019 - gif images rendering or displaying improperly in Firefox browser

Status: RESOLVED DUPLICATE of bug 239701

(Firefox :: General, defect)

Description

[John Davis]

Several .GIF images on several different websites do not display correctly using
the Firefox browser for Mac OS X (10.2.8). These gif images are always small
icon-type images. The images will have thin black lines through the image,
making them difficult to see. 

Examples of the images that do not display correctly are listed below. The first
image is a background image of a green arrow that appears on a Firefox/Mozilla
website:

http://www.mozilla.org/images/download_back.gif

This green arrow displays improperly when viewed as part of a page. But when
viewed directly at the URL listed here, the arrow DOES display correctly.

The following images are others that have the same problem. These images do not
display correctly in my browser when displayed on a regular page OR when
displayed at the specific URL's listed below:

http://www.geocaching.com/images/WptTypes/4.gif (small ghost icon)
http://www.geocaching.com/images/WptTypes/8.gif (blue question mark)
http://www.geocaching.com/images/WptTypes/5.gif (envelope icon)

http://www.geocaching.com/about/cache_types.aspx (a page where they are shown)

I have seen this problem at several other sites, but have not listed them here
because I don't remember where I saw them. 

I can send you a screen shot of what these gif images look like, if you wish. My
apologies if this problem has been addressed, but I could not find a bug report
that fit this description when I checked. Thanks.
