Hi hiral2cool,

That is very strange. I think this has to do with the ico file being enabled or disabled in about:config ? Try to disable javascript and restart the browser. You can still access it from about:config or by installing an add-on.

about:config

1. In the address bar, type "about:config" (with no quotes), and press Enter.
2. Click "I'll be careful, I promise"
3. In the search bar, search for "javascript.enabled" (with no quotes).
4. Right click the result named "javascript.enabled" and click "Toggle". JavaScript is now disabled.

To Re-enable JavaScript, repeat these steps.

Add-ons

You can alternatively install an add-on that lets you disable JavaScript, such as

• No-Script (to disable JavaScript on a per page basis, as required)
• QuickJava (to easily disable and enable JavaScript, automatic loading of images, and other content)
• SettingSanity (adds back removed options for JavaScript, Advanced JavaScript Settings, loading images, and showing the Tab Bar)

Thank you and I hope this helps!

I try all but none Work now what is Next....

The Big Developer Mozilla Firefox.. cant slove this Small Problem its Disdisgusting.. thing..

Could be this CSS rule in chrome://browser/content/tabbrowser.css

.tab-icon-image:not([src]):not([pinned]),
.tab-throbber:not([busy]),
.tab-throbber[busy] + .tab-icon-image {
  display: none;
}

Add code to the userChrome.css file below the default @namespace line.

• http://kb.mozillazine.org/userChrome.css

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

.tab-icon-image:not([src]):not([pinned]) { display: -moz-box !important; }

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

and if u have clearly showing the tab icons then give me some screen shot that i know is my problem or firefox by default problem

Firefox uses the chrome protocol to access internal files and also files from installed extensions.
You can paste such a link in the Firefox location bar to inspect such a file.

• Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist.
• Use a plain text editor like Notepad to create a (new) userChrome.css file in this folder (the names are case sensitive).
• Paste the code in the userChrome.css file in the editor window and make sure that the userChrome.css file starts with the default @namespace line.
• Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.

Otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file.

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Here showing the moz Box where is the Icons ?? look at this http://screencast.com/t/i4vmvm85YJv

- There is the Icon [src] but where i dont Otherwise Chrome also not Show icons on Tab so there is icon [src] but where ? - here is my Configuration Setting for userChrome.css

http://screencast.com/t/BQE8rdfK0o

what next ??

Those pages do not have an icon as the src is missing, so you get the default icon and that is an empty box. specify a new default icon as well

I have code like this to cover more cases:

#tabbrowser-tabs .tab-icon-image:not(src),
.sidebar-placesTreechildren::-moz-tree-image(leaf),
.bookmark-item:not(src):not([container]):not([type]){
 list-style-image: url("chrome://global/skin/icons/folder-item.png")!important;
 -moz-image-region: rect(0px,16px,16px,0px)!important;
}
