My default is plain text mails. Because many others often send html mails, this add-on is very useful to view them without changing my default reading style. To load the remote contents, you've still to click on "show remote content", which requires another click on a different location on screen.

Since the merger between Thunderbird and Thunderbird esr (24.2.0) and up I miss the message header button of this add-on, only the other tool bar buttons are available to me yet.
