SABnzbd has the Watched Folder feature. Any NZB file you put in this folder will automatically picked up as a job by SABnzbd.
So when you download an NZB file with your browser you need to save the NZB to the watched folder. This often can require a lot of clicks to select the proper folder. There is an easier way. You can tell Windows to execute a fixed action for each downloaded file.
1)
Create a Windows batch file (.cmd), e.g. use Notepad to create d:\bin\nzb-copy.cmd Of course, replace MY_WATCHED_FOLDER with the path of your Watched Folder.
@echo off
copy /y %1 "MY_WATCHED_FOLDER"
2)
Open a command prompt and type in:
ftype NZBFile="d:\bin\nzb-copy.cmd" "%1"
assoc .nzb=NZBFile
3)
Next time you download an NZB file with the browser, tell the browser to "execute" the file instead of saving it to disk.
The browser will then copy the NZB file directly to the watched folder.
