Filters don't work very well
Because Firefox's junk filtering works very poorly (compared to Eudora, which I used until a year ago), I supplement the junk filtering with filters. An example: An email came in from a spammer that called itself "Gigabrite" in the From field. I created a Filter to move the email to the Trash folder. Then I ran the new filter on the Inbox, and the email wasn't moved. Sometimes it works, sometimes it doesn't. (I am certain that I am filling out the New Filter page correctly.)
Now, I know that spammers can fool people in the BODY of an email by using HTML to insert and then hide random characters in words, but that isn't possible in the From and Subject fields, is it?

Firefox is a web browser and doesn't do email.

The first line of defense should be your email provider's spam filter on the server. For what slips through there and gets to Thunderbird, the built-it junk mail controls are your best bet. It doesn't work out of the box though, it needs to be properly trained to work reliably. http://kb.mozillazine.org/Junk_Mail_Controls
Trying to filter spam with static filters is a battle you can't win. I wish you good luck with that.

Pardon me. I meant to say "Thunderbird", not "Firefox".
Whether filtering spam with static filters is a battle I can't win or not, that doesn't change the fact that the filters don't always work.
