Building

Simply download the contents of the repository and pack the contents (sans git data) into a .zip file. Then, rename the file to .xpi and drag into the browser.

Download

You can grab the latest release from the Official Web Site.

Customization

Due to the security restrictions on the network error file, adding things like settings and options is impossible through normal means. Instead, you may create a custom version of the extension with your own personalized background image, icons, and element positioning. For more advanced changes, such as choosing a different search engine or adjusting the countdown time, you'll have to edit the source code yourself.

You can’t perform that action at this time.
