Your computer runs on XP? Browser is Firefox and you can't get MSN messenger to work? Was it working, and now doesn't? Re-install it. Did it never work? Check with Firefox to see you're up to date. Oh, and make sure all your other downloads (MS, Java, etc.) are all up to date. Just keep checking all sites for downloads. Should work fine.
