I am running firefox 3.6.3 in ubuntu 10.04. I am trying to access remotely my security dvr by using the address "admin,1:xxx.xx.x.xxx" the x's being the IP address where the dvr is installed on a network. I am getting the message "This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection." I have looked on the forum and have added the line "user_pref("network.security.ports.banned.override", 9000-9013");" to the prefs.js file as suggested. I still get the same message from firefox after having done this. I assume that I am using the correct protocol in the address bar, "admin,1" being the default user and password for my dvr. Thank you in advance for any help offered to solve this problem.
