I've gone into the Options and set the .SGF file to open with Smartgo. It refuses to do that. Clicking on a link to a .SGF file simply opens the file as text in a new tab. Since this didn't work, I tried to set firefox to download it instead, because then I can use the window's filetype associations to open it. It won't download the file unless I actually right-click and save-as on the link. This is tedious when viewing lots of these files. I even set it to Ask me after I saw the the Download option didn't work. It doesn't Ask me. What is going on here? Also I am using firefox 23 EDIT: It seems to be website specific. Some websites will allow me the option to open it in Smartgo, others will just open it in a tab as text. What is causing this discrepancy and can it be surmounted through browser settings? An example website to showcase the issue is: http://igokisen.web.fc2.com/wr/lg.html clicking on any of these links will not download, open, or ask about what you want to do with the file.
