When this page loads, you will be asked if you wish to install Hotbar.  Tick “yes” if you wish to fit one of the skins featured on this page or at the Hotbar website.  To fit the skin of your choice, simply click it and it will install on your browser  automatically.  If you selected “no” when prompted the first time, you will be asked again if you wish to install Hotbar.  The installation process takes only about 15 seconds.  Thanks to Hotbar for offering this wonderful facility and thanks also to Nick Brickell for introducing me to them.
