Hi MGRANT50, could you give a little more detail on how Firefox is involved?

For example, some websites coordinate with a locally installed program through a plugin. I don't see any proprietary plugins in your plugin list, so if a plugin is needed, that could be the reason the website can't connect with the local program.

Speaking of plugins, your Acrobat plugin is out of date. To update, either:

(A) Inside Adobe Reader / Adobe Acrobat, use Help > Check for Updates

(B) Install the last updater for the XI series from

Hello jscher2000.......thanks for responding

DigitalPersona is an installed add-on which Firefox disabled because it didn't have a digitally signed certificate (although the add-on has been running cleanly for years. Don't know if FF changed their requirements?)

Unfortunately Mozilla doesn't have a signed version of DP in its Ad-on Site and I can't determine how/where to get a signed version from DigitalPersona/Crossmatch

Add-ons needed to be signed in Firefox 48 and later. But the problem just came up recently?

Hi jscher2000

Yes, this situation just arose on Jan 1, after years of no problems. The issue does not occur every time I boot-up, just sporadically.....but I can't identify a pattern that precedes the "reader not detected" error message from FireFox.

The steps/article that you reference from Crossmatch doesn't seem to cover my version of DigitalPersona and I'm still not able to make contact with anyone at Crossmatch.
