Lightning 2.6.1 bug solution Rated 3 out of 5 stars

I also experienced the same issue with 2.6.1 not working in the Linux enviroment with Thunderbird 24.0. As suggested I found and downloaded 2.6 and applied this downgrade to Thunderbird. It works fine now. My question here is HOW do I STOP it from updating... Each time I restart my system I find 2.6.1 re-installed. Is there some way like making the directory only writtable by root or something similar. Any help would be greatly appreciated.

This review is for a previous version of the add-on (2.6.1).
