Eilana,

          The default column order used in Thunderbird places the Subject before the Sender.  This can be changed simply by rearranging the order in which the columns are displayed in your inbox.  

          The Mozilla Enhancements Add-On allows you to rearrange the columns after hitting NVDA+H.
