Nice, but breaks in TB5 Rated 1 out of 5 stars

I used this to display click-able links for the X-Antispam-Training-Spam X-Antispam-Training-Nonspam headers that got added by our upstream spamfilter (SURFMailfilter), which is based on Can-It Pro.
Too bad that the plugin does not work with Thunderbird 5, therefore I have to give it a poor rating.

This review is for a previous version of the add-on (0.8.3).
