I have toolbar icons that are downloaded from the web I want to use them in Firefox. I have the latest version of Firefox. I keep seeing a reference to a "show" button but I do not seem to have this either. Show how can I get my icons onto the toolbar palette? Also How can I change the Icons picture to existing ones? An example is the icons for the persona all look alike, so I would like to make them individual so at a glance I know which is which. So again how do I import and change toolbar icon appearance? Thank you for your time in advance.
