Great idea, how about the width?This review is for a previous version of the add-on (1.0.1-signed). This user has other reviews of this add-on.
Do you have some special width in mind? FFs default scrollbar width? Scrollbars would look like on this picture, if they would get FFs default scrollbar width: http://imageshack.us/photo/my-images/441/26199121.png/
