Christmas is one of my favorite times of the year. It is the only time that I get to spend with most of my family, due to our busy schedules and lifestyles.
To that end, I wanted to use a Christmas Firefox Theme. However, there aren’t any really good minimalist ones out there. So, I found some directions a couple of years ago from TwisterMC that work great.
- Find your userChrome.css file.
- Quit Firefox completely by selecting File > Exit in the toolbar or pressing the X in the upper right-hand corner of the browser.
- Download the background you like best and save it in Firefox’s chrome folder.

- Open up the userChrome.css file in any text or css editor and add these lines of code:
- Start Firefox and see if it worked.
/* Use a background image for the toolbars:
(Substitute your image file for background.gif) */
menubar, toolbox, toolbar, .tabbrowser-tabs {
background-image: url(”background.gif”) !important;
background-color: none !important;
}
Make sure to change the .jpg or .gif name to correspond with the one you downloaded.

If everything worked, you should now see candy cane stripes or Christmas lights behind the navigation buttons!
Want something different?
Create or use your own images and use the same code above to place your image behind Firefox’s toolbar.
