Comment 2 for bug 102848

confirmed.

the reason is that the file http://www.zeldman.com/favicon.ico is too large for
whatever stores the favicon in the bookmarks file.
i noticed this when i did the following.

i downloaded and installed the extention that allows me to select a favicon for
a bookmark that has none.
i downloaded http://www.zeldman.com/favicon.ico to my desktop
i used the extention mentioned above to make the bookmarks icon the one i
downloaded and saved to my desktop.
it gave me an error saying the file from http://www.zeldman.com/favicon.ico was
too large.

so..
i opened http://www.zeldman.com/favicon.ico with microangelo icon editor.
there was more than one icon in the file. multiple icons 16x16 and 32x32 all at
different color settings.. 256.. 16.. true color.. etc.
usually having a couple sizes or color settings isn't a problem but this icon
had just about every combination imaginable.. and it was very redundant on Mr.
Zeldmans part.

i've just checked http://airbagindustries.com/favicon.ico and same thing..
it COULD be that these icons have a windows XP color setting that uses alpha
transparency.
