Change the window icon

You can change Firefox's default window icon to any icon you want, by following these steps:

1. Go to the folder you installed Firefox in (e.g. C:\Program Files\Mozilla Firefox\) and then go to the subfolder chrome.
2. While in chrome, create a new subfolder called icons, then go to that folder and create yet another subfolder called default. The full path to this folder could be C:\Program Files\Mozilla Firefox\chrome\icons\default\.
3. Choose the icon you want to use (on Windows use .ico files, on Linux use .xpm files) and then place it in this folder and rename it to main-window.[ext], e.g. main-window.ico on Windows and main-window.xpm on Linux.

In addition to the main window, you can also change the icon on the Bookmark Manager and JavaScript Console. The icon names are bookmark-window.[ext] and jsconsoleWindow.[ext], respectively.

After this is done, restart Firefox and you should be able to see your chosen icon in the title of the browser windows.

an icon set that springs to mind is the GSM one. It has a copy of a blank icon, which you should rename as above.

And you can reshack the icon out.

Also: this has been asked multiple times in this group and general discussion (the old custo forum) and both have a search function.

i really don't remember the old custo forum though...
