I get recurring messages:

"SeaMonkey can't connect securely to sdp-si.com because the SSL protocol has been
 disabled."

SSL is enabled in preferences.

the sequence
# cd ~/.mozilla
# chmod -R 755 *
# chown -R <me> *
# chgrp -R <me> *

sometimes corrects the situation for an hour or so, seldom longer.

This problem makes seamonkey unusable on many websites.
