Re: [Opensc-devel] Chrome gets stuck and firefox won't open until stopping/restarting pcscd or unplugging CAC reader

Hi,

ref. "firefox will not open"

This seems to happen when the OpenSC module is defined in the 
"cryptographic module settings */ ***Security Devices" (don't know the 
exact naming in english for Firefox/Thunderbird)

*and* something is not perfect with the specific card driver running for 
OpenSC.

Due to recurring traffic between smart card and Firefox/Thunderbird 
(even if seemingly not necessary) I'm used to remove the OpenSC module 
from "Security Devices", and only add it when required.

Then recently, I tested the (obviously not properly working) Windows 
build of my external card driver, unnoticed that the Win-OpenSC v0.20.0 
complete install automatically adds the OpenSC module as security device 
via autostart, and  => Firefox did not open !

I don't have that "firefox will not open" problem with Kubuntu 18.04.5, 
for which the card driver build works well (even with 
OpenSC-0.21.0-rc2), irrespective of "Security Devices".
