+A simple add-on that adds a link to the longdesc under images that provides one.
+
+Maybe you want to look at this other extension for longdesc https://addons.mozilla.org/en-US/firefox/addon/longdesc/
+
+The source code lives at https://github.com/Rik/longdesk
+
+*Disclaimer:* I have no opinion on whether the longdesc attribute should or should not exist.
+I'm just tired of having to look through the source code every time I want to see a friend's explanation of a picture.
+This add-on has only been tested on http://www.nota-bene.org/Mise-en-abyme-a-carreaux
+
+Also, this is my first add-on ever so…
