you need to be more specific about what you have exactly downloaded. Is it a *.tar archive, *.bz2 or *.gz or ...
Also, is it an update for a firefox plugin? Those are usually handled by firefox itself. You just need to set the appropriate option. If it is an update for firefox itself then this should be handled by your system's package manager. Unless you want to upgrade to new version of firefox, which is not in your systems repositories. This, however, is strongly discouraged since this will most probably raise dependency issues. Judging from your post you certainly won't be able to resolve them.
So please post what exactly you have downloaded, your host system and why you think you have to do a manual upgrade.
