Since I updated to Firefox 4.0 I no longer can use the fingerprint scanner to log into websites. I get a message saying the protocol dpql isn't associated with any program. It was working fine upgraded. What do I do now?

The scanner works fine with Explorer and worked fine with Firefox before the upgrade. I find it disconcerting that you upgrade something that then changes how I have to use my computer in ways that have nothing to do with Firefox. At least we should have been warned prior to the upgrade that this was going to happen.

Id this the HP SimplePass Identity manager or Digital Persona fingerprint reader? If it is, the company that make the fingerprint reader have abandoned it. For more details see https://support.mozilla.com/en-US/questions/799388
