Caused by Bindwood extension to enable UbuntuOne sharing bookmarks (maybe linked with proxy settings?). As Douglas Baigrie said [https://answers.launchpad.net/ubuntu/+question/128771 here]:'' To obtain the username and password for your local couch db (which is where the bookmarks are stored with Bindwood) execute the following command as your normal user account:'' awk '/localhost/{split($3, parts, ":"); print "Username: " substr(parts[2],3); print "Password: " substr(parts[3], 0, index(parts[3], "@")-1)}' ~/.local/share/desktop-couch/couchdb.html"
