These are links on my Firefox links bar.  When I visit some sites they put an icon next to my link.  My links shown, except for Google, are pages on my computer with a series of links specific to that title.  For example the Web Cams link goes to a page I created that is filled with links to web cams.  Ditto for the Radar site, it's filled with weather related links.  I  have a link to NOAA on my page and when I clicked on it, it put  the NOAA icon next to my Radar link.

Is there a way to avoid this or get rid of these darn icons?
