I believe the last update (.16) broke my way to change the background color of the folder and message pane.
I used this userchrome.css
/* Folderpane & Messagepane */
background-color: #C9C9C9 !important; }
however now every other line has a white background.
i tried several other methods of changing the background, but it always had a similar result in that every other line wasn't affected by the changes.
Is there a new way to do this ?
