I am not cutting your rating down because this seems to be a great add-on,I am running firefox 3.0 and the problem I am having is that I can not delete group? In other words once it is added it is there for life the delete has no effect on this.
If you have an explanation for this please post it.
Only the FEEDS group that contains all your feeds can't be deleted. See https://www.mozdev.org/bugs/show_bug.cgi?id=18704.
