I spent 3 and a half hours wrestling with the NSS command line tools and the assorted certificate utilities trying to get my XPI signed. All tools returned success, but Firefox showed "Author not verified" every time I tried to install the XPI.

I downloaded this addon and 30 seconds later had a signed XPI that works properly.

Highly recommended.
