Firefox doesn't do email, and thus doesn't have any "message filters". It's strictly a web browser, not a "Suite" like Opera, SeaMonkey, or the old Mozilla Suite.
If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.
If your problem is with Mozilla Thunderbird, see this forum for support.
