I had to downgrade the extensions to 3.106. Since 3.107 there is something wrong. No buttons in address book.
Between connector release 3.106 and 3.107 are massive changes in /chrome/content/inverse-library/sogoWebDAV.js. I assume there sleeps the bug. Greetings Sven -- users@sogo.nu https://inverse.ca/sogo/lists
