SABnzbd has worked perfectly for a longtime. Recently whenever I add a new nzb. Another tab is opened in Firefox instead of putting new nzb in open SABnzbd tab. Also new nzb isn't in queue when computer is restarted. How do I fix? Problem may have started after upgrading from 0.6.1 to 0.6.15? Also upgraded to Firefox 12 recently. But not sure if either upgrade caused problem?
