Its Christmas celebration time and we have already covered Christmas themes for Windows 7, Vista and XP. Now we have an awesome theme for Firefox. Christmas Holiday Browser is a nice add-on which brings in the Christmas celebration to Firefox. Apart from theming Firefox, it also gives access to relevant Christmas content. You can easily change the background of Firefox with a click of a button.
There are few backgrounds available. The only problem the add-on creates is lesser screen space for websites, as it takes lot of space for its images and sidebar (sidebar can be turned off).
Nevertheless, a nice add-on for all Firefox users.
