I have bookmarks without icons. Can I install some other .ico or .png, or .jpg file as the default icon for the bookmark. I can save file to my computer but can't transfer it to my bookmark. I have "Roomy Bookmarks Toolbar" installed. In Internet Explorer I could save all my icons to some location and then direct all my bookmarks (change icon) to that location to find specified icon. Can I do this anything like that in Firefox?
