When logging in on my bank, Firefox also loads a box with "You have chosen to open ibank.dll which is a document from https://[bank name site]. I can still log into my account, but the extra window is annoying. This happens only on Firefox. It does not occur if I log in from Explorer, Opera, or Safari. I use an iMac.
