Hello Elmar, Sorry when I sound offensive but I really think that everything possible has been said. This mailinglist has a daily-business todo and was not designed for discussions. Please use the official archlinux forum[1], the archlinux-general mailinglist[2] or one of the archlinux channels in freenode[3] for it. Furthermore I think that the problem is maybe more netstat or firefox specific. Maybe you ask the developers of both tools as well. This mailinglist's main task is to inform subscribers about newest vulnerabilities. Please do not reply on this mail. So we can get back to our daily business. I hope you can understand my complaint. There are a lot better channels to discuss this stuff. Thank you very much and best regards, Chris [1] bbs.archlinux.org [2] arch-general@archlinux.org [3] irc.freenode.org (#archlinux,#archlinux-security)
