Firefox's theme site (update.mozilla.org) currently includes around 60 themes for the talk-of-the-town new web browser. The installation of these themes is just a few clicks away.

From the theme site click the 'Install' icon below the theme description, click 'OK' to confirm, and when the progress bar completes (in Firefox's theme window) the new theme is installed. Click 'Use Theme' and restart Firefox to complete the process.

At OSDir.com you can view these themes applied to the full Firefox window. Check it out.
