invalid certificate Rated 3 out of 5 stars

We use a self-signed certificate and I can't get past that warning. I can view it, but there's no "accept" button as there is with mail accounts.

This review is for a previous version of the add-on (0.10). 

This is a Thunderbird issue; please have a look at the FAQ entry for this problem at <https://answers.launchpad.net/lightning-exchange-provider/+question/125207>.
