Don't work with FF 3.0.5 and the new migrate Feedburner-Account:

http://code.google.com/intl/de-DE/apis/feedburner/awareness_api.html

Servers and Ports - HTTPS

Note that the Awareness API is only available via HTTPS, on port 443. An
example URL for accessing the awareness API would be https://feedburner.google.com/api/awareness/1.0/GetFeedData?uri=blogspot/tuAm

This review is for a previous version of the add-on (1.3).
