Hi peeps. A little help needed if no one minds? I am having trouble download .nzb files. When i try i get an error via firefox saying: ...nzb could not be opened, because the associated helper application does not exist. I used to used Unison to open this file be have now deleted this and started using i grab and nzb drop. I don't know if the problem is with my firefox settings or what? Ive had a look but cant seem to sort it out... Thanks in advance for your help as i know how helpful you peeps can be on here!
