If a website is not whitelisted then you won't get a preview, but you can still install a persona if you click the Allow button on the sliding bar at the top that Firefox shows to ask for permission.
Preview only works if you use the default theme and only on websites that are whitelisted as an allow exception in " Tools -> Options -> Security > Warn me when sites try to install add-ons: Exceptions". If you visit a website like that offers personas then you can hover an example image to get a preview impression of how it looks like. In Firefox 3 versions prior to Firefox 3.6 you can use the Personas extension to add support for personas. Normal themes require a restart to take effect. Personas add a background image (skin) to the user interface part of Firefox (toolbars and Add-ons bar ) that can be changed without restarting Firefox. Personas are an example of such a lightweight theme and this implies that you can't use personas with a custom theme. Such themes allow to make changes to the default theme and do not replace that theme completely like regular themes do. Firefox 3.6 and later versions have native support for lightweight themes.
