Immunization in IE vs. Firefox

[sunnybacon]

Hi there.
I'm a bit confused about what the difference is between Spybot's Immunization in IE and the immunization in Firefox.
Firstly, which browser out of the two is "immunized" better?
Secondly, the SDHelper description says it is "Internet Explorer bad download blocker". If it only blocks IE bad downloads, should I revert to IE instead of using my current browser, Firefox?
Ideally, I'd like to stick to Firefox.
Thanks in advance for any help and info. :euro:
