I have noticed for about two weeks that emails from known non-profit sites requesting advocacy responses/comments are becoming increasingly slow to connect or not connecting at all and that they are being flagged as insecure in Thunderbird. Is this new? Is it, in fact caused by Mozilla, as a matter of security? Are there bad actors mucking about? The slow/no response thing is frustrating since I don't have a lot of time to engage in this activity. My internet connection is via GreenLight. Thanks for any enlightenment. Emily Metz
