OK the best textarea editor I've tried today is "It's All Text!", found here: https://addons.mozilla.org/en-US/firefox/addon/4125 https://addons.mozilla.org/en-US/firefox/addon/4125 It reliably places a little blue "edit" button below the lower-right corner of the text area. When you click the button it reliably grabs any text in the textarea and puts it into your external editor. When you save changes in the external editor, it automatically refreshes the text area with the new content. I also like "It's All Text" for security reasons. It puts temporary edit files inside your own ~/.mozilla/firefox/$profile/itsalltext directory, with access set to owner-only (chmod 700). In contrast, the Texto plug-in puts temporary edit files in /tmp, granting read access to group and other (chmod 644). I'm not too comfortable with that.
