Spice Up that Boring about:blank Page in Firefox

The blank tab page in Firefox is just a plain white boring nothing – until now. Using the Stylish extension for Firefox, we can set a custom style for the page, and even embed images into the style to make it really look great.

If you are feeling ambitious you can easily create your own style, or you can skip down further to take a look at some of the styles already created by the people at UserStyles, some of which are really sweet.

Creating Your Own Style

I’ll assume you have the Stylish extension for Firefox already installed, so click on the icon in the status bar, choose Write Style and then Blank Style.


Give your style a description, and then paste in the text I’ve provided below. This will make a blank white page with your image in the center…


@namespace url(;
@-moz-document url(“about:blank”) {

* {
      url(“data:image/png;base64,INSERT BASE64 ENCODED IMAGE HERE”);

To insert images into the style, you have two choices:

  1. You can directly insert a link to an image hosted on a server by replacing the url() line in the CSS with this one:


  2. You can base64 encode an image into text instead so that it’s embedded into the stylesheet, which is the best option for most people. How do you do this? There’s any number of web-based converters that will handle this, including this one that I found: Binary File to Base64 Encoder / Translator –

Just copy the converted text into your stylesheet where indicated, and it’ll work. If your image isn’t PNG format, you should change the image/png line to reflect the correct type. (most of the converters will give you the correct format).

    i didn’t like the converter you proposed. this is one that actually works:
    overall, great idea!

    Nathalie: Wow, great link. I’d been using the “data: URI kitchenâ€? at

    For the record, this hack borks the new Gmail’s reply box.

    This has never been a great idea, if you take a look at how about:blank is used.

    Hi. This is an awesome tutorial. Keep it up!

    However, whenever I reload(close and open) my FireFox browser, the stylish disappears and all I get is a blank page when I open a new tab.

    I am wondering if any of you encounter this.

    Nonetheless, great tutorial. Step by step. Awesome!

    Adding an image to about:blank does not harm your browser in any way, if you actually read the link you posted, you’ll see that the other things it’s used for are basically place holders. In other words, if someone uses about:blank on their web page you’ll simply see your awesome image there instead of a blank spot. Which just makes it all that much more brilliant.
