In 4.0 how do I change graphic atop browswer window?
3.6 allowed me to customize the appearance of the area at the top of the browser window with a graphic that appeared behind the browser tabs, icons, etc. But with the new layout of 4.0, the image I had installed has a dark area behind the Page Title that causes it to be unreadable. And in 4.0 I can't find the setting to remove or change that graphic image. Any suggestions?
That will be a Persona, you can change it by installing another one from http://www.getpersonas.com
You can also switch to the default theme, open the add-ons manager, then in the Appearance section click on the default theme in the list of themes, then click the Enable button.
