Sir. Community is a theme for Firefox. It has shiny yellow construction signs as the background of each button. This theme was created by Andrew Shay (xXSonyBoy4lfeXx). Sir. Community can be downloaded from Mozilla's secure website by clicking the download links on the right. The latest version is highly recommended.

To install you can go to Sir. Community's addons page and that will install it automatically or you can click one of the links to left and if it doesn't auto install you can download it to your desktop, then go into Firefox and click Tools, Addons, then drag the downloaded file into the addons box.
