Sometimes tabs do not produce the site owners favicon when bookmarked and only a "globe" icon is displayed in the Bookmarks Toolbar. Can anyone recommend a foolproof favicon editor that works and has understandable instruction on how to work it. I've tried two or three and cannot see how to use them or the instructions do not seem to have any relevance to what I see on my screen. If you do recommend an add-on, can you also give an idiots version of how to use it. Thanks.
