do you only have a 256 color desktop? (looks like)

256 colors: no, I just saved the screen shot at reduced color depth (to save
your download time). All other bitmaps, icons etc. are perfectly shown/drawn.

This icon fixes this problem

This icon uses 256 colors instead of 16M. It fixes this problem under WinNT and
looks the same as the original one on other variants of Windows.

This file should be copied to

Could someone please review it ?

The problem still exists for the final 1.2
Please fix this in 1.2.1
This bug has a fix. Attachment 97596 [details] fixes this problem (see comment #9 ). Can
we request a review for cheq-in ?

Bug still present in Mozilla 1.2.1
The above attached icon fixes the problem.

The problem is *not* solved by attachment 97596 [details].  The icons in the task-switch
bar (the one that appears under Windows when you press Alt-Tab) are still
corrupted.  I think that's because they are larger than the taskbar icons.

Forgot to mention: I have TrueColor.  The problem never occurs with the first
Navigator window.  It increases (more "speckles" in the icon) for each Navigator
window I open, also if I first close the other Navigator windows.  For example,
start Mozilla with browser and mailer.  Browser has perfect icon when
Alt-Tabbing.  Close browser.  Press Control-1 in mailer to open new browser. 
Icon of new browser has three corrupted pixels.  Close browser.  Press Control-1
in mailer to open new browser.  Icon of new browser has five corrupted pixels. 
And so on, and so on, ever more corrupted pixels.  I've tested this up to 25
corrupted pixels.  Don't know if I can get more.

Icons on Windows usually contain multiple image definitions embedded into the
same file. For example, the icon on attachment 97596 [details] has 32x32(256 clrs) and
16x16(256 clrs) images. Are you sure this icon does not solve the problem? It
did for me, and also for other people (see comment #10 )

You have to:

1) Download attachment 97596 [details]
2) Copy it over <MozillaHome>\chrome\icons\default\main-window.ico
3) Restart Mozilla

Also you can download and install an improved (more icons, and better
resolutions) version of mozilla Icons from

Yes, this icon fixes the original problem for me too.

The problem described in Comment #17 doesn't seem to be the same one to me.

It's a shame we missed release 1.3 for this: it's so ugly and so simple... I
should have found this bug page earlier. Please check it in ASAP! Thank you!

Task bar icon for the first Mozilla Navigator window is still corrupted. But the
icons in the task-switch bar (the one that appears under Windows when you press
Alt-Tab) are all ok. 

Are there any reasons why this simple "patch" is not applied? (except lack of

Daniel Mario (#19),

I downloaded the icons from, and now my problems have disappeared.

(BTW, I added this comment, but I do not know whether buggiquette allows to use
a bug-reporting system as a discussion forum.)

Icon with True color and 256 color in 32*32 and 16*16 versions.

The regular icon sems to have some sort of error in it, I haven't looked well
yet, but here's a version with 16 and 32 pixel versions in 256 AND true color

This new icon is fine for me (16 bits display). It works for both the taskbar
and the alt-tab menu. I have replaced the main-window icon by the one from the
download manager and the reported issue doesn't occur in that case either. I
mean that the main-window.ico *could* be the only broken one.

The new icon from comment 23 works perfectly for me (1600x1200 32 bit
TrueColor). It's the only one I've replaced. So please review it and check this in.

Reporter, can you also check if the last icon is also working as expected for you?
Thanks in advance!
The only problem I see with the last icon ( Attachment 118264 [details] ) is that its
format is different from the other mozilla icons.

Mozilla Icons are:

3638 bytes long with two images
16x16-256clr + 32x32-256clr

But the last icon ( Attachment 118264 [details] ) is

7782 bytes long with four images
16x16-256clr + 16x16-TrueColor + 32x32-356clr + 32x32-TrueColor

The first icon ( Attachment 97596 [details] ) has the same format as the ones thar come
with Mozilla

Grey Hodge,

Since you created the icon, can you please reply to comment #27? I hope you
don't mind I put your address in the Cc: list. (Is there another way I'd better
have used?)

Thank you again for your help!

Same as last icon, minus the true color formats. 256 color only

Thanks actually, I meant to CC myself previously.

Ok, I actually meant to include a true color version, as there was a slight
improvement, but here's a version without true color icons. It's the same byte
size, but there are binary differences. This one is 100% valid, to be perfectly
safe. Reporter: Try this, see if the problem persists.

I am still seeing this on 1.4RC1.  However, the icon in attachment 97596 [details] fixes
the problem for me.  Looks like it didn't get checked in.

Still happens on:

Mozilla 1.5b
Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.5b) Gecko/20030827

Solution described in Comment 19 fixes the problem.  Is there a reason that this
isn't getting checked in?

We need someone to make a quick review here and check it. Jag, can you help us
out? This won't block the release but drivers would consider an approval request.
