I applied a fix I found which allowed me to download attachments in Firefox but based on the reading some information about it, the fix may not work for all files but should work for most files. If anything, a future update to SMF may correct it better. But yeah, it should work now.
I'll look into the redirection stuff now and should hopefully figure something out by the end of the weekend.
Edit: Nevermind, figured out how the redirection was done, now going to zfgc.com will do what the redirection did before, but instead of going from the news.php file of the Infini's old site system to Windy's site system it just goes here.
