I missed the Toggle Preview Pane terribly. I'd didn't know how to "up the maxVersion in the rdf to 6.0.0" as per mod_wastrel's glimmer-of-hope-for-me post. Here's a link to instructions: http://www.techsupportalert.com/content/how-update-firefox-thunderbird-addons-new-release.htm

Toggle Preview Pane is installed now and working just fine.
