Firefox 16.0.2 doesn't download rar files properly
Hi,
I got a report from a user of our website that they can't download rar files... I checked and indeed left-clicking to download a rar file doesn't work; FF doesn't seem to recognize the mime type and loads the file in-browser instead of prompting to Save As.
You can see this on an example here: http://www.sorcerers.net/Games/IWD2/Anarion_Custom_Portraits.rar
Zip files download fine. We've confirmed that this only happens in FF, so I assume it's a bug...

Such issues happen if the server isn't configured correctly and the files are send as text/plain if Firefox opens the page in a tab as text like in this case.
You will have to instruct the server (cloudflare-nginx) to send the RAR files with an appropriate MIME type to make Firefox save the file.
That could be a CloudFlare issue then since that's the CDN we started using a few days ago. But why would it work fine in all other browsers except Firefox? That doesn't make sense...
Firefox always respect the MIME type if a server sends such a MIME type in the response header like in this case.
Other browsers may change there behavior according to the file extension or content sniffing, but Firefox doesn't do this and fails in cases like this where the server isn't configured properly.
