While I admit I don't really quite understand what all the below means, in the ''userChrome.css'' file I added this to make the font size larger on the left side where all the folders are listed: /*** Folder pane ***/ #folderTree > treechildren::-moz-tree-cell-text(selected) #folderTree > treechildren::-moz-tree-cell-text(selected, focus) { color: rgb(0,0,0) !important; font-family: Arial !important; font-weight: bold !important; font-style:italic !important; background-color: rgb(82,205,255) !important; border: rgb(102,117,255) 1px solid !important;} #folderTree > treechildren::-moz-tree-cell-text { color: rgb(0,0,0) !important; font-family: Arial !important; font-size:9pt !important; font-weight: regular !important;} Is there a corresponding code or string to make the font size larger on the subject side? And if so, in which file does it go? Thanx, Herb
