Another operating system is the Linux. Its operating systems can support themes depending on the window managers and the desktop environments. For example is the IceWM which uses the themes to customize the taskbar, the window borders, and the time format. The WindowMaker can also store colors that are good for icons, menus, and for the window-borders in a theme.
The GNOME and KDE both use two independent sets of themes. The first one is to alter or change the appearance of the user interface elements such as the buttons, scroll bars or the list elements  and another one is to customize the appearance of windows such as the window borders and its title bars.
Some applications such as the Firefox and Google Chrome can either support or have supported a form of any theme. Firefox and thunderbird support themes either through complete themes or by lightweight themes which are formerly called Personas or complete themes.
The lightweight themes are simply used to the background images for the toolbar of the Firefox tool bars, while the complete themes are a lot more than that. They have more power to modify the Firefox's appearance.
The Google Chrome version 3.0 allows the themes to alter or change the appearance of the browser, on the other hand, the Internet Explorer 5 and its other immediate successor allows the background picture of the tool bars for them to be well customized according to the wants and style of the users.
