It is insane to hardcode /var/tmp.
Considering the comment, they probably think it's insane to put /tmp in RAM, and since web browsers are often used to download huge files and /tmp is the default non-hardcoded dir, they're trying to avoid users complaining about failed downloads.
Doesn't Firefox download in $XDG_DOWNLOAD_DIR by default these days?
