HI - I've been forced to use retro versions of Thunderbird for a few years in order to continue using the other BCC addon. I updated to Big Sur yesterday and discovered my 60.8 Thunderbird no longer worked. I had to upgrade to Thunderbird 78 and, BCC addon no longer works. Then found your new addon, and WONDERFUL, works a dream. I am SO RELIEVED. There are some functions when sending emails, such as mistakenly sending bulk emails by CC, that can really cause problems, it's so useful to have this add on. Thanks very much for doing it. Barry
